KD600M is an advanced multi-channel dielectric loss tester employing frequency conversion anti-interference technology and a built-in 10kV/200mA high-voltage power supply. It supports simultaneous measurement of four samples, CVT ratio testing (35-500kV), and LCR measurement. With CVT C1/C2 self-excitation testing and low-voltage shielding for grounded CVTs, it provides comprehensive insulation analysis. The unit can store 200 test records, and the large LCD screen provides Chinese/English menu operation.

1. CVT self-excitation method test: Simultaneous measurement of C1/C2 capacitance and tgδ with a single connection;
2. Reverse wiring low-voltage and high-voltage brightness functions: Measurement of C11 at 10kV without disconnecting the grounded CVT lead;
3. External voltage and external CN measurement functions;
4. CVT ratio measurement: 10-10000 range for 35-500kV CVTs, with an accuracy of 1%;
5. Multi-channel simultaneous measurement: Simultaneous testing of dielectric loss in four samples;
6. Insulation resistance test: PI, DAR, and IR measurements;
7. Automatic LCR measurement: Inductance, capacitance, and resistance testing;
8. Frequency conversion technology eliminates 50Hz power frequency interference in strong electromagnetic interference environments;
9. Overcurrent protection: Prevents sample short circuits or breakdowns;
10. Built-in standard capacitors and high-voltage power supplies reduce on-site wiring;
11. Large LCD screen, Chinese and English menus, easy to operate.
