ESG-MATIC is the new outdoor SF6 insulated pole-mounted MV (24 - 36 kV – 630A) sectionalizer.
Product Description
It includes 3 integrated voltage transformers (LPVT) and 3 currents transformers (LPCT) for measurements, with programmable control logic and automatic intervention. All this ensures an even more functional service continuity thanks to the automatic reconfiguration in reduced times. Most of the MV OHL faults are transient or self-cleaning and usually last a few seconds. ESG-MATIC works in coordination with the main circuit-breaker or recloser during the fault interrupting time. Thanks to ESG-MATIC, it is possible to recognize the fault segment of the line. The logic is current and voltage based: • it is an automatically controlled circuit-opening device; • it counts the fault current operations and the lack of voltage of the upstream protection (circuit-breaker or recloser); • it operates after a pre-selected number of faults current operation; • it automatically isolates the faulted section of a distribution feeder.
