NEED FOR JEF EARTHING HEALTH ASSESSMENT AUDIT (Bangalore, India, Other Countries)

Normally Earth Electrode (Pit) Resistance alone is measured periodically. Electrical System is deemed to be safe with a low Earth Electrode Resistance. The Integrity of Earth Conductor (Strip) between Earth Electrode and Equipment is rarely checked. Hence Breaker may not trip even if Earth Electrode Resistance is low. In reality, timely operation of the breaker (Electrical Safety » ) depends on the resistance of earth loop formed by equipment earth conductor (Strip), earth electrode and phase conductor. System modifications and Deterioration of Earthing System » can render the original design calculations of protection system (breakers) invalid. JEF’s assessment methodology » covers this crucial gap by checking all the above parameters, thereby ensuring timely operation of the breakers to prevent accidents/damage » . Carried out on live systems without Shutdown using sophisticated meters and practices.
