Understanding Normally Energized (NE) and Normally De-Energized (ND) Relays in 3-Phase Voltage Protection Systems
When protecting electrical systems from voltage fluctuations, choosing the right type of relay plays a crucial role. Two popular configurations are Normally Energized (NE) and Normally De-Energized (ND) relays. This blog will walk you through their working principles, differences, applications, and how they are used in real-world voltage protection setups, especially in the UAE market.
