OVERVIEW

HPD300 reverse power protection relay is widely used in marine Genset fields and land Genset fields.
The power direction, instead of flowing predominantly from the generator to the Bus, as usual, flows back to the generator from the current system when the generator lost excitation or another failure occurs. That is to say, the generator works as an electromotor. HPD300 reverse power protection relay is in order to avoid the above situation and provide protection when an overpowering situation occurs.

PERFORMANCE AND CHARACTERISTICS

• Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with frequency 50/60/400Hz;
• Collects 3-phase voltage, 3-phase current, frequency, and power parameters.

TYPICAL DIAGRAM

INSTALLATION DIMENSIONS

1. Output And Expand Relays
   All outputs are relay contact output types. If need to expand the relays, please add a freewheel diode to both ends expand the relay’s coils (when coils of the relay have DC current), or, add a resistance-capacitance return circuit (when coils of the relay have AC current), in order to prevent disturbance to the controller or others equipment
2. AC Input
   Current input must be connected to the outside current transformer. And the current transformer’s secondary side current must be 5A. At the same time, the phases of the current transformer and input voltage must be correct. Otherwise, the current of collecting and active power maybe not be correct.
   Note: When there is load current, the transformer’s secondary side prohibits open circuits.
3. Withstand Voltage Test
   CAUTION! When the relay had been installed in the control panel, if need the high voltage test, please disconnect the relay’s all terminal connections, in order to prevent high voltage into the relay and damaging it.
