|How to calculate the Short Circuit Impedance in Transformer?
|what is the formula for AH?HOW CAN IT CALCULATE
|What is the type of electrical earthing recommended in hard
|when voltage gets down the current of motor increases. but
according to Ohm's law voltage is directly proportional to
current. plz explain
|working principle of induction motor is similar to
transformer. but what makes it to rotate? then why the
|two 100W/230V bulb are connected in series. what would be
the voltage drop across 1 bulb
|we have two 11/.433 kv. distribution Transformer rating as
1000 kva & 500 kva , i wants to run parallel both transformer.
both transformer impendence voltage is 5.24%, How can we run
both t/f, & how sharing the load
|what is vibration?
|what type of motor is used in fan
|i am using star-delta connections with reverse/forward
direction motion of the 75hp induction motor.What should be
the ratings of Main,Delta and Star contactors and why?
|A group of machines (wind turbines) connected with 33KV
feeder and each machines are having individual VCB. The 33KV
feeder connected with 110KV/33KV substation. The 33KV feeder
tripped by over current at Substation and fault recorded at
Substation as OC-R&Y phase. Same time the group of machines
VCB tripped by over voltage, the fault recorded voltage was
above 66KV by numerical Under/Over voltage relay. While grid
drop time, this much of voltage hike is possible?
|I WANT TO know WHICH WAY IS BETTER FOR CONNECTION BETWEEN
POWER TRANSFORMER AND MAIN DISTRIBUTION PANEL.
1-IS BETTER WE USE CABLE?
2-IS BETTER WE USE BUS DUCT?
my transformer rate power is 2500KVA
