TENSE PHASE FAILURE (PHASE PROTECTION) RELAYS
A phase failure relay which is also known as phase protection relay prevents three-phase motor failure due to line or motor overheating. The relays are designed to protect the devices with sensitive operation voltage against failures due to line voltage.
It is important to remember that phase failure relays do not ensure direct protection. These devices only detect abnormalities such as excessive voltage, low voltage, inverse phase order or phase drop. Then, the relays send a signal to the circuit breaker components. Thus, the phase failure relays help the healthy operation of the motor and increase system efficiency. Prevent any disruption due to failures. Decrease the electrocution or fire risks.
Things to consider when choosing a Phase Protection Relay
As phase protection relays protect engines and prevent malfunctions, you should be careful when choosing one. Material quality and manufacturing technology are surely important. However, what you should primarily take into consideration when buying a phase control relay are technical details.
Technical values such as operating voltage, operating frequency, operating range, operating power, operating temperature, asymmetry, error cooldown, and phase order control should definitely be suited for its environment and your system.
When choosing between models that meet technical adequacy, ease of use is important. We should say that it would be better if you look through adjustment buttons and gauge screens on digital phase control relays.
