can I connect step down transformer(25KvA,240V Phase to
phase)to output of online UPS(15KvA,440V PHASE TO PHASE)
Load connect to TRANSFORMER is 13KvA,240V PHASE TO PHASE.
please brief if it is wrong
HOW TO CUT A CAKE IN 8 PIECES IN 1 STROKE
what will happen if there is a voltage leakage or current leakage in an electrical train
One B.O.T Unit ??
why we not connect the 12 V batteries in parallel to get the more backup supply for an UPS ? wheter off line or on line UPS ?
What are the reason of unbalanced secondary voltage of HT transformer 33kv/6.6kv ? Incomming voltage is balanced.33kv each secondary voltage 6.6 kv 6.4 kv 6.4 kv At no load conditions.
what is inductance function?
what is the meaning of ceiling voltage in Generator exciter?
HOW TO CHECK THE VECTOR GROUP OF A TRANSFORMER YD11?
why we step down the voltage from 440 to 220 in machines
HOW DOES THE PERCENTAGE DIFFERENTIAL PROTECTION WORK IN POWER TRANSFORMER
there are a transformer and a motor. both are connected to 3phase, 415 Volt, 50Hz power supply. Both are working with induction principles. Then, why, motor is rotating and transformer is not rotating.
