How to Measure Shaft Voltage in High-Efficiency Three-Phase Motors
Measuring shaft voltage in three-phase motors, especially high-efficiency ones, can be quite intricate. First, you need to ensure you have the right equipment. Typically, professionals use Fluke meters or similar high-precision devices. The shaft voltage meter must have a high input impedance, at least 10 megaohms, to get accurate readings. During my experience in the …
