QLDJS-HA Dielectric Loss Tester
The QLDJS-HA Dielectric Loss Tester is a complete device used for measuring dielectric losses in high-voltage electrical equipment such as transformers and circuit breakers. It has used frequency conversion technology to ensure accuracy of the measured values in areas of high interference. With anti-interference performance, a user-friendly LCD touchscreen, several additional protection systems, and the focus only on on-site testing at the substations make this instrument stand outmine.
