ESG 80-2 – Earth Fault Locator (Receiver)
Earth Fault Locator ESG 80-2 for pinpoint location of sheath faults. This instrument is a highly sensitive galvanometer and is provided with an amplifier. Interfering DC voltages can be suppressed with a compensation circuit.
The pinpoint location method:
Pinpoint location of a sheath fault is based on the step voltage method. The test current coming from a pulsed DC source up to 5 kV is flowing into the ground at the point of fault and results in a maximum step voltage at the fault. This peak is located with the two earth spikes and the ESG 80-2 earth fault locator. When approaching the fault position, the step voltage increases and decreases after the fault with a change in polarity.
Technical features:
- Active mode with amplification and compensation for repressing external voltage.
- Passive mode for use without battery power supply 6 sensitivity ranges
- Utmost measuring sensitivity for faults in the A range.
- Easy handling and fault direction indication
- Variable earth spike distance for high sensitivity, even far away from faults Sensitivity adjustable in 5 steps
