HDPG-830 microcomputer generator ground protector

Overview Characteristic Selection Guide The HDPG-830 generator ground protector applies to: one-point or two-point rotor ground protection for medium and small capacity generators in the non-rotary excitation mode and rotary exication mode with rotor voltage led out; and rotor ground protection for all kinds of generators within the 100% range. 1.Rotor protection 2.Stator ground:The fundamental harmonic zero sequence current protection applies to the wiring mode of a generator bus with a leading-out cable. The fundamental harmonic zero sequence voltage protection applies to the wiring mode of a generator-transformer unit. The third harmonic zero sequence voltage protection and the fundamental harmonic zero sequence voltage make up 100% rotor ground protection together. Ordering instructions Provide the following upon ordering: 1. Name, model and quantity of the device. Please specify any special requirement differs from our standard product. 2. Voltage class. The operating power supply for any device is intended for both AC and DC purposes, with 110V and 220V inputs; the 220V version will be provided unless otherwise specified. 3. Communication port: The device standard communication configure is a single 485. If needs dual RS485 network which shall be specified. 4. Ratings of key parameters For a protector, provide the nominal rated current (1Aor5A) For a device with the zero sequence current protection function in a low-current ground system, provide the rated zero sequence current (0.2Aor0.02A) 5. Term and place of delivery, means of transport 6. Other terms shall be negotiated.
