The earth leakage guards of the ELG-series controls the dielectric resistance between the medical supply circuit and the earth potential. The typically arranged protective measures against insulation fault on the building power supply (such as ground fault circuit breaker) may not principally identify possible insulation defects on the output side due to the galvanic insulation through the IMED isolating transformer. This leads to a potential danger for the patients or the operating personnel. The earth leakage guards of the ELG-series close this security gap reliably by clearly warning against insulation faults. For this, the leakage resistance is controlled for undercut of a limit value. If this occurs, the ELG warns optically as well as acoustically.
