Hand-cranked analog insulation tester in anti-magnetic aluminium body — no batteries required. 100 V to 5000 V.
— Industries · Applications
Substation Commissioning
Substation commissioning requires a full suite of T&M instruments — from pre-energisation insulation and earth resistance tests through to protection relay commissioning. EPC contractors rely on instruments that are robust, accurate, and carry traceable calibration. CIE instruments are selected by commissioning teams for their proven field reliability.
