Existing single-phase induction motors exhibit low starting torque. Moreover, during accelerating time and at a steady-state, they produce a significant level of torque pulsations which gives rise to noise and…
Winding resistance test measurements detect various faults in motors and transformers: shorted turns, loose connections, broken strands, and malfunctioning tap changer mechanisms. Studies conducted by IEEE and the Electric Power…
This is the commonly seen issue in pumps. When the pump is not able to deliver the required pressure it is considered to be a delivery failure problem. Steps to…
Friction loss essentially refers to resistance caused by fluid flowing through pumps, pipes, and fitting. That resistance results in decreased pumping pressure and decreased fluid velocity. Friction between the adjacent…
A solar simulator is also known as a Solar array simulator (SAS) is simply a programmable DC power supply that provides illumination approximating natural sunlight. The purpose of the solar…
What Is Blocked Rotor Test? A blocked rotor test is conducted on an induction motor. It is also known as short circuit test, locked rotor test or stalled torque test.…
