Electric power savings

Hi everyone

 We have a electricity crises in South Africa, I do Spike control and electric power savings in South Africa.

i started in 2012 we had excellent results in the past 8 years saving  you on your electricity bills and more.

We have the new intelligent MSA 30kw spike control unit that save you up to 30% on you electricity bills

we have a lot of critics that say this doesn't work but we proof them wrong , the secret to our units is that we have to do a check on your power load we found the unit work 100% for the customers with electricity bills above R750 per month say from R800 to R3000 per month.

We have the MSA 30kw and  the MS1 all single phase units from 30kw to 90kw.

We have the MS3  three phase units from 200kw to 1000kw.

This units do Power factor and harmonics on your power lines  

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.

Fines currently being imposed on electrical power consumers, who have a poor power factor

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!

The reason why Power Factor Corrections only recently became a hot topic in Southern Africa

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.

Is Power Factor Correction a new technology?

Power factor correction equipment dates back to the 19th century and is based on proven scientific concepts.

The benefits of installing Power Factor Correction equipment if you are not being billed for maximum demand (KVA) or for reactive power consumption

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.

The reduction of carbon footprints by installing Power Factor Correction Equipment

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.

What happens when a system’s voltage is lower than the capacitor rated voltage which is part of a Power Factor Correction System?

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.
