Product Advantages
Frequency conversion anti-interference guarantees accurate measurement even under strong interference. High precision is achieved with input resistance below 2Ω, effectively eliminating test line errors. Multi-level safety protection covers HV/LV, grounding, CVT, and misoperation prevention. CVT self-excitation allows simultaneous C1/C2 measurement without rewiring, while the reverse wiring low-voltage shield accommodates bus-grounded 220kV CVT. Up to 100 data groups can be stored, complemented by an RS232 interface and a thermal printer.
Main Applications
This dielectric loss tester functions as an insulation loss analyzer, a high voltage tan delta tester, a dielectric dissipation factor test kit, a Dielectric Dissipation Factor Tester, and a Capacitance and Dissipation Factor Tester. Typical applications include transformers, CVT bushings, insulation oil, solid materials, and on-site high-voltage equipment.

Frequently Asked Questions (FAQ)
Q1: Why are my test results unstable?
A: Poor hook contact, inadequate grounding, or high air humidity (>90%) are the most common causes. Ensure 0Ω grounding and scrape off paint or rust at the grounding point.
Q2: How does the dissipation factor tester (model: NRJS600) handle CVT measurement?
A: Use CVT self-excitation mode. Connect the low-voltage output to any secondary winding, as no polarity requirement exists. The dissipation factor tester (model: NRJS600) then automatically measures C1 and C2 in a single test without requiring the high-voltage wire to be lifted.
