Green LED (Un) indicates supply voltage OK. Yellow LED (R) indicates active relay output. What is the abbreviation for Over Voltage Relay? What does OVR stand for? OVR abbreviation stands for Over Voltage Relay.

In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.: 4 The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current, overvoltage, reverse power flow, over-frequency, and under-frequency.

The time setting is used to avoid tripping due to any transient disturbances. 16V Over-Voltage Relay More Precise, Less Temperature Sensitive, Protect sensitive Avionics equipment: Piper: 450-397, 484-183, 550-380, 450-393 Beech: 138-1 Wico: X-17621 B00289-2, B00339-1 Electrodelta: OS75-14 Delco Remy: 1115831 Prestolite: FOC-4002B Zeftronics: ACU PN R15V0N or ACU P/N: R15V0L has this Over-Voltage relay built in Over voltage protection is used to protect the synchronous Generator/transformer/alternator form high voltage. Generally, overvoltage occurs due to sudden load through off, elevated grid synchronized voltage, AVR malfunctioning, power transformer taps changer failure, lightning strike on the transmission line, turbine over speed etc. the power system must be isolated when the system voltage high.

Each limit (over-/under-voltage) has its own relay output (R1 Over and R2 Under) and there is an adjustable time delay for each relay output (Tt1 and Tt2), adjustable between 0.3-30 s. H3USN also checks for neutral interruption. Green LED (Un) indicates supply voltage OK. Yellow LED (R) indicates active relay output.

The relay does just what it says and protects these delicate systems from spikes in voltage.

If the voltage rises above than this level for the set amount of time then the tripping command issued by the relay and hence the system is isolated. The time setting is used to avoid tripping due to any transient disturbances. 16V Over-Voltage Relay More Precise, Less Temperature Sensitive, Protect sensitive Avionics equipment: Piper: 450-397, 484-183, 550-380, 450-393 Beech: 138-1 Wico: X-17621 B00289-2, B00339-1 Electrodelta: OS75-14 Delco Remy: 1115831 Prestolite: FOC-4002B Zeftronics: ACU PN R15V0N or ACU P/N: R15V0L has this Over-Voltage relay built in Over voltage protection is used to protect the synchronous Generator/transformer/alternator form high voltage.
