How does it work?
When transported, electricity is subject to numerous fluctuations and losses of charge as well as variations, leading to electricity peaks, exploitable by our electrical devices. Thus a part of the electricity delivered to our households is delivered in the form of exploitable overcharges, yet billed. These electricity peaks make u pay and consume more, however once a MS1/MS2 unit has been installed the electrical currents stabilize
The MS1/MS2 stabilizes the voltages and also reduces currents when appliances are switched on. The MS1/MS2 prevents the appliances from generating additional heat – which is a result of excess energy, that excess energy is wasted as it doesn’t help to improve performance. You however still pay for that energy even if wasted. By stabilizing the voltage and currents the MS1/MS2 will ensure that no energy is wasted and thus optimizes the energy usage of all electrical equipment in your house.
Power factor is the percentage of electricity that’s delivered to your house and used effectively, compared to what is actually wasted. For example, a 1.0 power factor means that all the electricity that’s being delivered to your home is being used effectively by your appliances. However, most homes today have a 0.77 power factor or less. This means that about 77% of the electricity that is coming through your meter at your home is being used effectively; the other 23% is being wasted by your inductive load caused by some appliances (air condition, and any other appliance with Motor’s is inductive load ). With a low power factor, the utility company (Eskom) has to deliver more electricity to do the same work. Now, with the MS1/MS2, it helps to increase the power factor in most cases to 0.99, and increasing the effective use of your electricity and lowering your meter reading.
Yes install to your DB Board by an electrician
Yes. We provide a 2 Year off- shelf guarantee
No. the rule applied is one MS1/MS2 per Distribution Board. Therefore only one MS1/MS2 is required for your entire household.
This is achieved due to the fact that the power supplied by Eskom, passes through one point known as the Neutral bar. The electricity is then distributed to each circuit. This circuit is continuous and interlinked therefore, by installing the MS1/MS2; you are successfully affecting the entire household.

What is a Power Factor?
In the simplest terms, power factor is the measure of how effectively your electrical equipment converts electric current (supplied by your power utility) into useful power output. In technical terms, it is the ratio of Active Power (also known as Working Power and measured in watts or kilowatts (W or kW)) to the Apparent Power (measured in volt amperes or kilovolt amperes (kVA)) of an electrical installation.
The Active Power consumed by an electrical device is used to perform a useful power output such as heat, light, mechanical energy, etc.
Inductive devices (such as electric motors, transformers, welding units, lighting ballasts and static converters) also consume Reactive Power (measured in volt ampere reactive or kilovolt ampere reactive (Var or kVar)) in order to generate a magnetic field. This magnetic field does not perform any “useful” work, but is required in order for the device to work. The reactive current drawn by an electrical device lags 90 degrees behind the active current drawn by it.
The Apparent Power drawn by an electrical installation is the vectorial sum of the Active and the Reactive Power drawn by the installation.
Non-technical explanation of Power Factor
Various analogies have been used to describe poor power factor including the following:
Horse Pulling Cart
A cart on a railway track is being towed by a horse that is off to the side of the railway track. The pull directly between the horse and cart is the apparent power (kVA). The effective work by the horse is the cart moving down the track, being the active or true power (kW). The pull at right angle to the track does no effective work and represents the reactive power (kVAr).
The horse would ideally pull the cart directly down the railway track so the apparent power equals the real power, thus minimizing wasted energy.
Beer with Froth
A large beer is ordered to quench the thirst of a thirsty individual. The beer has some froth on top that does nothing to quench the individual’s thirst – this represents the kVAr (reactive power).
The beer does quench the thirst – this represents the kW (real power).
The total contents of the mug (the bear and the froth) represent the kVA or apparent power. The glass must be full of beer with no froth for the person to gain maximum benefit from the glass of beer. It is the same for maximum efficiency with power as the system should not be drawing any kVAr (or froth in the analogy).
Power Factor Correction
Power factor correction is the process of improving a low power factor present on a power system by means of installing power factor correction capacitors and in so doing, increase the ratio of active power to apparent power.
When the apparent power is greater than active power, then the utility provider must supply the excess reactive power AND the working power.
Power capacitors act as reactive power generators and they reduce the total amount of current a system draws from the grid.
Frequently asked questions
The power utilities in most industrialised nations charge users a penalty when their power system’s power factor drops below a certain level, usually below 0.90. This power factor surcharge covers the electric utility’s cost of supplying your power system with additional reactive power.
In South Africa, no “fines” are imposed as yet, although Eskom intends to introduce fines in the near future.
Some South African municipalities (i.e. City Power) do charge for excessive reactive power consumed, which is a form of “fine”. City Power charges for all reactive power consumed below a power factor of 0.96!
Electricity has until recently been a cheap commodity in South Africa (and Southern Africa in general). The payback period of an investment in power factor correction has therefore been fairly unattractive. The recent tariff hikes have significantly reduced the payback periods and will continue to do so in the short to medium term.
Power factor correction equipment dates back to the 19th century and is based on proven scientific concepts.
There is no financial benefit under these circumstances BUT, it could free up capacity on your supply, allowing you to add more equipment and in so doing increase production or avoid relocation to different premises with a larger power supply.
Power factor correction reduces the total current drawn from an electrical distribution network (which affects systems such as the power stations, distribution grid and supply transformers). In so doing, the heat or transmission losses incurred on these systems are reduced. Power factor correction therefore only has a minor impact on your carbon footprint.
The reactive power of a capacitor, as shown on its data plate, is always indicated at a specific voltage. If the voltage of an installation is lower than the rated capacitor voltage, then the output if the capacitor is negatively affected.
For example: a capacitor of 10 kVAr rated at 440V will only provide 8.3kVAr if the system voltage is only 400V!
This is an important factor which must be taken into consideration when determining the reactive compensation requirements of an electrical installation.
If you connect the correct value of capacitors in the supply to an induction motor, you will reduce the current flow from the supply to the point where the capacitors are connected. If you measure the current in the supply between the capacitors and the motor, you will find that the current does not change. The current into the motor is independent of the connection of the capacitors. The efficiency of the motor is unchanged.
In most instances, not. The motor losses are not changed so the temperature rise of the motor remains the same. However, if you install a suitably rated capacitor directly onto the motor, you will reduce the current flowing through the supply cable and in so doing, reduce the volt drop on the cable. This in turn can result in a reduction of the total current drawn by the motor, which will reduce the heat (Watt) losses (=I2R) of the supply cable.
Manufacturers of diesel-electric generator sets usually indicate the maximum output of their equipment at a specific power factor, usually 0.8.
This means that if you purchased a 1000kVA generator set, you actually bought an 800kW system. Installing power factor correction would in theory allow you to increase the output of the set to 1000kW. The alternator will be able to cope with this load, but the diesel engine will not.
Another potential problem is that under conditions of significant and sudden load reductions (for example a major fault in the system), the power factor correction system will not respond fast enough to reduce its reactive power output to match the reduced requirements. The excess reactive power generated by the power factor correction panel has nowhere to go and the system voltage will increase dramatically. This usually results in significant damage to the generator, the power factor correction panel and the associated electrical distribution system. Generator suppliers usually clearly indicated in their warranty conditions that power factor correction which is in operation with the generator will render their warranty null and void.
No, the addition of power factor correction may reduce the current drawn by your residence, but this will not result in a reduction of your electricity costs. This is due to the fact that you are only being billed for your active power consumption (kWh) and not for maximum demand (kVA) nor for your reactive power consumption (kVArh).
Power factor correction in a residential application is primarily only used to prevent the main incomer circuit breaker from tripping by reducing the total current drawn. The power factor correction panel supplies most of the reactive current drawn by the inductive components in your residence, and in so doing, reduces the total current flowing through the incomer circuit breaker.
There is no financial benefit in doing so; there is only a “comfort” benefit.
Harmonics
- They are a distortion in an electrical network created by non-linear electrical devices such as VSD’s, DC drives, soft starters, UPS’s, etc
- Harmonics are a component of a periodic wave which has a frequency which is a multiple of the fundamental frequency of 50 Hz: i.e. 150Hz is third order harmonic frequency;
- They are a steady-state phenomenon, not a transient condition;
- 3-phase non-linear loads typically create 5th, 7th, 11th and 13th harmonic ;
- 2-phase non-linear loads typically create 3rd order harmonics and higher order multiples of 3;
- Total harmonic distortion of a waveform (THD) = the level of voltage or current harmonic distortion existing at any point on a power system.
Does Power Factor equipment generate harmonics?
Power factor correction equipment does not generate harmonics but it can amplify existing harmonics present in a network, which will affect sensitive electronic equipment in its vicinity. It is therefore recommended that harmonic blocking reactors be fitted in series with capacitor banks when existing harmonic levels are elevated. The blocking reactors present the harmonics from reaching the capacitors and can therefore not be amplified by them.
The typical symptoms of excessive harmonics present in a system
- Inexplicable electronic component failures;
- Overheating electrical cables;
- Protection equipment such as circuit breakers and fuses tripping for no apparent reason.
Acceptable harmonic distortion levels
A total harmonic distortion (voltage) or THD (V) of 2.5% and a total harmonic distortion (current) or THD (I) of 15% are usually considered safe levels.

Intelligent Precise Compensation Power-Saving System
Spot welding loads fluctuate extremely rapidly and consume large amounts of reactive power. Due to high current changes caused by the near-instantaneous reactive energy consumption, large voltage drops are produced. These sags reduce weld quality and decrease welding productivity.
Harmonics pollution increasingly becomes a dominant power quality problem, Mainly due to modern loads. Coping with this issue using capacitor bank has Two alternatives:
De-tuned Systems
In de-tuned systems, reactors are installed in series with the capacitors and

frequency below the first dominant harmonic (usually the 5th). The middle graph on the right shows the capacitor/network amplification factor and the shifting of the resonance frequency from near the 5th harmony to near the 3rd harmony.

Tuned Systems
In de-tuned systems, reactors are installed in series with the capacitors and
If harmonic filtration is needed, on top of resonance prevention, tuned reactors are applied. The capacitor/reactor filter is tuned to absorb particular harmonics and reduce the Total Harmonic Distortion (THD). The bottom graph on the right shows harmonic filtration using tuned system: the voltage THD was reduced by more than 70% (8.8% to 2.5%) and the dominant harmonics (5th and 11th) were reduced by 75%.frequency below the first dominant harmonic (usually the 5th). The middle graph on the right shows the capacitor/network amplification factor and the shifting of the resonance frequency from near the 5th harmony to near the 3rd harmony.
When connected directly to the line, large inductive motors consume very high current during the start-up period (six times higher than steady state operation).
This high current consumption can lead to significant voltage drops on both the low and high voltage sides of the transformer, which interfere with other loads, reduce initial torque and increase start-up time.Our single phase home units MSA work in a intelligent way to stop spikes up to 30kw and electricity savings from
15% to 30%
