Megger EST 50 High Voltage Discharge Rod (50 kV max. 6 µF)
Safe 50 kV Cable Discharge for High Voltage Testing
The Megger EST 50 High Voltage Discharge Rod is designed for high voltage engineers and cable testing technicians performing dielectric testing, fault location and HV cable diagnostics.
After high voltage cable testing, cables can retain dangerous stored energy. The EST 50 discharge rod safely discharges and earths cables up to 50 kV, removing residual voltage before technicians handle or ground the circuit.
A built-in discharge resistor provides controlled damped discharge, limiting current while rapidly removing cable charge and reducing post-charging effects during high voltage testing. The rod is manufactured from fibreglass-reinforced plastic with extended safety clearance, ensuring safe operation when working around high voltage equipment.
The EST 50 model measures approximately 136 cm in length and is designed for systems up to 50 kV, making it suitable for professional HV cable testing environments.
Why use a high voltage discharge rod?
After dielectric or DC cable testing, cables can store hazardous electrical energy. A discharge rod safely removes this charge and provides visible earthing before technicians handle the cable, reducing the risk of electrical shock.
