MV Switchgear and HV GIS

ENGIS provides professional expert to perform on site test for switchgear yard and GIS with the guidance of Doble engineering.

We are also the dependable provider of MV switchgear testing services in Israel. While on-site, an on-line partial discharge (PD) survey on medium voltage switchgear and high voltage gas-insulated switchgear will be performed to identify sources of unwanted EMI, RFI, acoustic, etc. interference/concerns. The survey comprises scanning with a radio frequency interference receiver covering the range 0-1GHz. A PD location may well be carried out using ultrasonic detectors, high frequency current transformer (HFCT) or transient earth voltage (TEV) sensors to determine the location of any PD sources.
