This illustrates the power values and the increased maximum demand (KVA) and high reactive power (KVAR) due to a low power factor being achieved on the LV electricity supply of a UK manufacturing site.
The image has been taken from a Power Quality Survey provided for a customer.
The maximum demand KVA should be as close to the consumption KW as possible. There is a large divide between the two in the monitoring of the supply due to the large reactive power (KVAR) demand.
The second image illustrates an LV electricity supply with a good power factor. The reactive power (KVAR) as power factor correction equipment has been installed and is reacting to the reactive power demand of the business equipment.
The capacity KVA of the supply is increased and the maximum demand value achieved is much closer to the KW.
