Single-phase monitoring relays | Choosing the Right Protection Relay
Before you buy a protective relay, there are a few more things to bear in mind: What is the current used in your grid? It is essential to know what type of current is used in the grid for which the relay is intended: direct current, alternating current, single-phase, or three-phase. What incidents do you want to prevent? You can configure the relay to trigger when it detects certain faults or malfunctions that you have previously defined. The relay...
