if we have a industrial load of 400 kilowatts with 415 volt AC then how much total harmonic distortion (thd%) should be acceptable for steady power system.
1936an amazing situation was faced when an alive distribution panel with 415 volts and carrying almost 200Amps has become short and this metal cubical showing 220 volts against neutral and earth. to redress any confusion i checked the panel with help of single 200watts test lamp which also glowing with max.intensity b/w neutral & metal body of DB. amazing situation is that i hold the DB firmly more than once with necked foot means without insulated shoes but not received any electrical shock. whereas our all running gen sets neutral points also proper grounded and this short DB was completely earthed , this is beyond my understanding . any body explain how is it possible . our running gen set neutral also grounded firmly
1 2351Why we use two wattmeter during block rotor test and no load test of 3phase induction motor? And how can we understand the neat power requirement of from this test?
2 10615when measure the core loss of three phase distribution transformer or three phase reactor loss, one phase shown negative watt loss. why??
1932a 120 60 watt incandescent lamp has to be operated from 50 c/sec 1 phase ac supply. in order to do this a circuit element has to be connect in series with the lamp. which one of the following sries element is preferable.
