An industrial plant is supplied by a power utility company with voltage of 7.97 kV. To monitor the plant's performance and consumption, the utility company installed a potential transformer (PT) and a current transformer (CT) at the plant's premises. The specs of the transformers are as shown on Figure 1. The plant is drawing 2000 kW at 0.90 pf lagging,.
