High Voltage Discharge Rod (De-Energizing / Earthing Pole)

Discharge Rod Series

A discharge rod is used to safely discharge and earth high-voltage equipment after it has been isolated, ensuring that no residual or induced charge remains before work begins. Even after switching off and locking out, overhead lines, busbars, transformers, capacitors and cables may retain stored, static or induced energy. The discharge rod allows the operator to release this charge from a safe working distance, preventing electrical shock and arc events.

Key Features

  • Safely discharges residual or induced voltages before maintenance

  • Provides a controlled path to earth to eliminate stored charge

  • Essential for proving equipment is dead before contact

  • High-strength insulated fiberglass pole for working clearance

  • Durable copper / brass earthing clamp & discharge hook

  • Flexible insulated earthing lead with secure grounding point connection

  • Lightweight and easy to operate while wearing HV gloves

Technical Specifications

Component Description
Pole Construction High-strength insulated fiberglass
Discharge Hook Copper / brass high-conductivity contact head
Earthing Cable Flexible insulated cable to earth bonding point
Function Discharge & earth stored energy in HV equipment
Usage Voltage Model dependent (MV–HV systems)
Operation Manual touch contact from safe standoff distance
Safety Standard Suitable for utility & industrial HV safety procedures

Used only after lockout & isolation, as part of prove-dead procedure.

Where / When It’s Used

  • Discharging overhead lines after switching off

  • De-energizing substation busbars and disconnectors

  • Releasing stored charge in transformers and large inductors

  • Safe grounding of capacitor banks before maintenance

  • Earthing of HV equipment during fault repair or line work

  • Used by: Utilities, substations, HV contractors, mines, factories

Mandatory Sequence Reminder:

  • Switch off and isolate

  • Lockout & tag

  • Test for voltage

  • Apply discharge rod and earth

  • Begin work only after verified zero-energy state
