Question

Why we need to control the voltage of power system. Explain the methods in detail

Answer 1

,we need to control the voltage of power system because with the increase in voltage there will be increase in temperature and hence results in the wrong values

Answer 2

The voltage of the power system may vary with the change in load. The voltage is normally high at light load and low at the heavy-load condition. For keeping the voltage of the system in limits, some additional equipment requires which increase the system voltage when it is low and reduces the voltage when it is too high. The following are the methods used in the power system for controlling the voltage
