What is the multiplying factor if line ct ratio is 1000/1 and meter ct ratio is -/5 ?
You mean the meter is designed to give full / actual reading for CT ratio 1000/5 ? Then multiply by 5

Dear Sir, we met a disaster with our 62.5 kva genset, after rewinding we informed by our contract engg that due to return current coming in neutral & impropper earthing this happend. But after all set up & load balance we checked & found again we have about 20 to 32 amp return current on neutral. we have 12 airconditioner + 12 mini fridge on single phase line. Pl suggest any idea to solved this problem

Explain the operation of damper winding
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 mention the minimum IR value for different voltage systems
which of the following loss varies with the load a)hystresis loss b)eddy current loss c)copper loss d)core loss
What is the out put of a CT? How the ratio is decided ?
We have a 12MW power plant & we inject 5-6MW power to Orissa GRID. For this we have a 33KV/11KV switch yard having 12.5MVA power transformer. Some times we draw power during emergency. It is observed that during Export or Import for load less than 500Kw the power factor is decreasing to 0.3 . This is happening only during export or import. During island condition TG power factor OK.Our capacitor bank is provided with our Power plant auxilliary load. Please suggest how I can we improve our power factor during low load (GRID).
