What is the DEIF RMP-121D Reverse Power Relay?
The DEIF RMP-121D is a reverse power relay used for detecting and inhibiting the flow of power in the reverse direction. In a power system, reverse power results when a generator begins drawing power rather than generating power. This can cause a variety of serious problems, ranging from damage to generators to higher operating expenses.
The 238506.10 model guarantees the generator is disconnected in case of reverse power, safeguarding both the generator and the whole power distribution system.
How Does the DEIF RMP-121D Function?
The RMP-121D works by constantly monitoring the direction of power flow within a generator system. Upon sensing reverse power, the relay sends a trip signal to disconnect the generator from the power system.
Here’s a step-by-step simple explanation of how it works:
Power Monitoring: The relay continuously monitors power flow direction.
Reverse Power Detection: When power begins flowing in the incorrect direction, it detects the fault.
Trip Activation: The relay activates an alarm or automatically disconnects the generator.
Protection Guaranteed: The generator is securely isolated to avoid further damage.
