In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Say the word “analog” to most EEs, and thoughts turn to op-amps, power devices, I/O, or signal conditioning circuits. But, the system beyond the circuit is also full of “analog,” if we include ...

When grounding exposed non-current-carrying metal parts of motors and controller frames to prevent a voltage above ground in the event of accidental contact between energized parts and frames, what ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...
