17377Is it possible to run HT motor through LT VFD (LT VFD supply given to Transformer LT side and transformer HT side connected to motor)
1 3249Can we use the ceiling fan regulator to run drill machine having 2000 watt power consumption?
2 2573we have one pumping station and 4.6 MW 7 no.s synchronous motors.so there is no required HT capacitor to improve power factor.But we have two no.s of 25 Mva power transformer connect to distribute the power for motors connect with 220 kv line.So i have required the HT capacitor to improve power factor at HT side i mean power transformer bus side.So please suggest how much HT capacitor banks required for same.
1 1957If we says that current is flow only when there is closed path & neutral work as a return path for the same. Then how circuit is closed in three phase as no neutral available ??
