Description
Overview
GAOTek net insulation meter is mainly used in various AC, DC transmission and distribution system, power control panel and electric equipment for various industries such as marine, rail, aviation, chemical and explosive-proof, nuclear power, high to mid voltage equipment, power generator set and control engineering. It is high end meter, and suitable for complicated environment to measure electric or non-electric energy. Also used on low voltage equipment, construction or mechanical equipment, various AC, DC power distribution system, electrical control panel and equipment. It is mid, low-end meter, and suitable for universal environmental to measure electric or non-electrical energy.
Features
- DC net insulation monitor integrate indicating and monitoring
- Insulation resistance lower than preset value, alarm signal release
