  1. Purpose

The THT-FZG generator neutral grounding resistor cabinets are suitable for complete sets of equipment with high-

resistance grounding.Mainly grade for the generator voltage is from 6 kv to 20 kv. When the stator one-point

earthing occurs, It can limit the grounding current in a small value and effectively suppress arc grounding

transient overvoltage.

3 .Product feature

1) It is suitable for equipment with high-resistance grounding;

2) cabinet material : stainless steel plates or aluminum-zinc plates or cold-rolled steel plates

3) resistor material:electrothemal alloy grid element type is better than stainless steel.

4) generator neutral grounding resistor ark also equip single-phase disconnector so that it can isolate power

supply during the test and repairs.

5) our company has researched intelligent control unit which can monitor more data than counter and transfer the

data to the mainly control room.
