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,. Industrial Plant IA CB A VL = 7.97 kV PT CT (V) 1 kn 250 ΜΩ PT Specs: 7970-V:120-V, 60 Hz X₁ = 1721 02, R₂ = 1378 , X = 782 k X₂ = 1897 22, R₂ = 1602 (referred to its primary) CT Specs: 200-A:5-A, 60 Hz X, = 745 μΩ, R, = 136 μΩ, Χ = 307 ΜΩ X'₂ = 813 μn, R'₂=128 un (referred to its primary) ...
