Power Factor Correction
n addition to Active Power, many electrical devices also demand Reactive Power. In industries, motors (the common load) which give valuable work output use Reactive Power to maintain a magnetic Field essential for their operation. This reactive power is ex¬tra power but not useful energy, and because of this, power utility (UMEME) imposes additional charges in form of penalties related to the consumption of this energy.
POWER FACTOR (PF)
Power Factor is a ratio of Active power over apparent power and there is always a need to bring this ratio to near unity (1) this helps to avoid excessive penalties by the Power supply providers (UMEME). Industrial consumers, therefore, pay for the actual energy in Kilo-watt-hour (KWH) plus the above Reactive Energy. It, therefore, makes economic sense for the power user to reduce this extra bill to a
The most effective way of doing this is to introduce Power Factor Correction Equipment which provides a compensating Reactive power (to reduce the effect of reactive power). And the best way to achieve good results is to employ an Automatic Regulator which increases the power factor without presenting an executive capacitive to the supply.

POWER FACTOR CORRECTION RECOMMENDATIONS
By offering Power Factor Correction Recommendations, we can help ensure you’re getting the most out of your power.
Through careful analysis of your electrical system, we can provide a comprehensive report that includes recommended correction equipment, suitable installation locations, and the cost of not correcting your power factor.
For a proper analysis, a power quality analyzer installed in your premises for all your production periods can provide the end real-time parameters you require.
To help prevent equipment malfunctions in your facilities, we use sensitive power test equipment that analyze the amount of harmonic distortion in a power system and determines its source. Once the problem is identified, we’ll recommend the size and location of filtering equipment to mitigate the specific harmonic that is causing the trouble.
Standard operating features:
- LED indications with detailed legends
- Voltmeter to indicate input & Output voltage
- Auto manual operation
- Output voltage setting potentiometer
- Plug-in control cards
