WF-FZD Generator neutral resistance cabinet

The grounding mode of the generator neutral point 

1. neutral point directly grounding;

2. neutral points are grounded by low impedance.

3. neutral point ungrounded;

4. the neutral point is grounded by the arc suppression coil.

5. the neutral point is grounded by high impedance.

The main function of the grounding resistance of the generator neutral point

Limiting the fault current to burn the core of the generator.

The transient overvoltage limit is about 2.5 times the rated phase voltage.

Restraining the resonant overvoltage;

The limit of single phase grounding fault current is not more than 5-15A;

Improve the sensitivity of generator grounding protection, making the protection and distribution more convenient.

Use of the environment

Applicable to indoor;

Environment temperature: no less than -40 C, not more than +40 C

Altitude: no more than 5000m;

Relative humidity: not more than 95% (25 C);

Power grid frequency: 58~62Hz (60Hz system) and 48~52Hz (50Hz system);

The air in the installation area should not contain chemical corrosive gases and vapors, and there is no explosive dust.
