Description
Megger EST 50 Discharge Rod: Secure Earthing for 50 kV Systems
Safety in electrical substation testing starts with reliable charge elimination. The Megger EST 50 grounding and discharge rod is engineered to discharge capacitive energy safely before test connections are handled. Featuring a 100 kΩ damping resistor, it slowly releases stored cable charges up to 6 μF, neutralizing the dangerous post-charging effect without sparks or structural stress to the conductor.
Key Operational Safety Features
- Damped Discharge Technology: Avoids dangerous high-current arcs by limiting the discharge rate mathematically (t = R x C).
- GFK Insulation Tube: High-grade fiberglass-reinforced plastic ensures high insulation safety under humid or warm climates.
- Ergonomic Guard Ring: Clear handle marking ensures technicians keep their hands well behind the high-voltage threshold.
