I have 2500KVA transformer delta/star,13.8KV/380V provided with LV 4000A breaker. Already I have 2300KW motor feeder with a full load 90%. Is it possible to connect another 1600A from that breaker? If so how the calculation is done?
What consists of 2 or more thermocouples to be connented series?
1) why a dg set shows variation of power factor and load when synchronised with other dgs? 2)Why the load sharing is not become equal in all dgs?. 3)When a dg set will not run on auto start?
An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The rotor reactance at stand still is A 2 ohm B 1.25 ohm C 3.15 ohm D 2.25 ohm
