What is corkscrew rule?
Please give me a solid reason there are 2 ELCB's If we take Phase from ELCB NO:1 an Netural from ELCB N:2 why ELCB is tripping when we connect the Load?please brief me with detail
A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
In explosive and polluted environments which type of motors do we use?
what happens in a genarator when rotor supplied with ac instead of dc
what is power factor? whether it should be high or low? why?
A electrical meter has load 500 kw. In 2 hr what rading will come on meter.
why do we use 25kv supply for traction purpose?
what is the Excaste meaning of CT Saturation?? 10 P 20, 15 VA, what is the meaning of 10, & 20. if the CT polarrity changed what will happened?? what is the differece between measuring CT & Protection CT?? what is the Saturation Point of measuring CT & Protection CT??
why in an industry; machine having rated 200 h.p stopped after power factor is maintained above 0.97 lag by control panel in view-of energy saving
As per the theory current doesn’t flows in Neutral, but practically it is not applicable, explain why?
