Power Factor Meter Connection with Load.
The power factor meter determines the types of load used on the line, and it also calculates the losses that occur on it. The meter has one fixed coil which acts as a current coil. This coil is split into two parts and carries the current under test. The meter has two identical pressure coils A and B.
Power Factor is the ratio of working power, measured in kilowatts, to apparent power, measured in kilovolt amperes. Apparent power, also known as demand, measures the amount of power used to run machinery and equipment during a certain period. It is found by multiplying voltage (V) by current.
To calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA), and to calculate the ratio of kW/kVA.
The power factor formula can be expressed in other ways:
PF = (True power)/(Apparent power)
OR
PF = W/VA
