Last month, we saw how you can use vectors to define complex circuits and determine current. This month, we'll show you how to use vector diagrams and some simple math to calculate neutral currents in ...

Improper neutral-to-case connections can cause fire hazards, electrocution, improper operation of protection devices, and power quality problems. Therefore, it’s important to make them only at service ...

This article discusses many common misunderstandings about the function of the neutral wire and its relation to power problems. The subjects of dedicated lines, phase reversal, isolation transformers, ...
