In the ACB breaker capacity is 2000Amp but this each phase taken 1250 But total beldibg load is 600amp or 700amp watt is the problem
How to calculate the phase to phase clearness of HT /// LT bus bar?????
How to design the NGR Resistance
a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
how u select control transformer for a mccb panels or any panels?for expample we hav 440 volts maim supply and control volts is 230v?
What are the two types of compensation?
reason of diode failure in alternator
what is consequences of neutral and earth connect?
How to measure power in 2 or 4 or n phase circuit? Please give me a formula.
why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
How do we calculate the resistance per metre of single core aluminium stranded cable 19*3.25mm sheathed in pvc,at 15 deg C temperature?
Can you used moeller lzm1 mccb in a dc system with 125vdc and 20ka short circuit current , beside is it have 24 or 48 volt shunt ? Beside how long current can through from An MCB shunt contacts? (like Z7-AS 24 V)?
