MS-101G1dielectric loss tester

1. Features a self-excitation test method for CVTs, allowing simultaneous measurement of C1 and C2 capacitance and tgδ with a single connection.
2.  Includes reverse connection low-voltage shielding and high-voltage shielding functions, enabling non-disassembly 10kV reverse connection dielectric loss measurement of C11 even when the CVT busbar is grounded.
3.  Features measurement functions for externally applied voltage and externally added CN, as well as forward and reverse simultaneous measurement capabilities.
4.  Uses frequency conversion technology to eliminate 50Hz power frequency interference, ensuring reliable data even in strong electromagnetic interference environments.
5.  Overcurrent protection function prevents instrument damage in case of short circuits or breakdowns of the test sample.
6.  Includes a built-in standard capacitor and high-voltage power supply for convenient on-site testing and reduced wiring.
7.  Features a large LCD screen and simple operation with Chinese menu prompts guiding the testing process.
8.  The instrument's function interface includes corresponding wiring diagrams, greatly simplifying the connection process for the operator.
9.  Includes English and Chinese language switching capabilities.
