I. Basic Applications

A Resistive Discharge Rod is used in power systems to safely release residual charge on equipment or lines, preventing electric shock or arcing.

Common applications include:

Capacitor Banks

High Voltage Cables

Substation Equipment

High Voltage Testing Equipment

GIS/Switchgear

After equipment is de-energized, residual voltage may still exist. The discharge rod slowly releases the charge through its built-in resistor, preventing instantaneous discharge surges.

II. Working Principle

The Resistive Discharge Rod contains a high-value resistor. The discharge process is as follows:

1. The discharge rod is brought into contact with the equipment carrying residual charge.

2. The charge flows to the grounding terminal through the resistor.

3. The current is limited by the resistor, achieving slow and safe discharge.

Advantages:

Prevents instantaneous high currents

Reduces arcing and equipment damage

Improves operational safety
