An industrial consumer charged with the scheduled tariff of Rs.250 /kVA per month for maximum demand and 150 paisa per unit consumed for load factor of 60% and 80%. Find overall cost per unit at i) unity P.F. ii) 0.9 P.F. consider maximum demand of 50 kVA.
Answer : To solve this, we need to calculate the total cost of electricity consumption for an industrial consumer, considering the maximum demand (MD), load factor (LF), and power factor (PF) at ... tariff is based on kVA, and the load factor and total consumption determine the cost more significantly....
