A double circuit with dog conductor 66KV Transmission line from wind farm evacuation to feeding substation having capacity of 25MW for transmission. Can same transmission network be considered for further expansion of Power & how much in MW. If we need to expand next 10-15 MW more will there any augmentation is required in transmission network? Kindly reply asap.
give me a clear defination of inductance,and how can u calculate inductance of a motor
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
Please clarify 1. Icw: rated short circuit working withstand capacity 2. Icu: Rated ultimate breaking capacity 3. Ics: Rated service short circut withstand capacity 4. other specification of ACB
