Product Description

MY-108 automatic dielectric loss tester is a high-precision measuring device, especially suitable for on-site environments such as power plants and substations. It can measure the dielectric loss tangent (tg δ) and capacitance value (Cx) of various insulation materials, insulation sleeves, power cables, capacitors, transformers, and other high-voltage equipment on site under high frequency voltage.

Feature of MY-108 automatic dielectric loss tester
1. The instrument supports self-excitation testing of CVTs, allowing for simultaneous measurement of capacitance and tgδ of C1 and C2 with a single wiring connection.
2. It features low-voltage and high-voltage reverse-wiring shielding. When the CVT busbar is grounded, 10kV reverse-wiring dielectric loss measurement of C11 can be performed without disconnecting the wires.
3. It also features measurement of applied voltage and applied CN.
4. It also features CVT ratio measurement, meeting requirements for CVTs rated from 35-500 kV.
5. It also features multi-channel simultaneous measurement, enabling simultaneous measurement of dielectric loss values for four test units.
6. It also features insulation resistance testing, enabling polarization index, absorption ratio, and insulation resistance testing.
7. It also features automatic LCR measurement, enabling measurement of inductance, capacitance, and resistance.
8. It utilizes frequency conversion technology to eliminate 50Hz power frequency interference, ensuring reliable measurement data even in environments with strong electromagnetic interference.
9. It also features overcurrent protection, ensuring the instrument is protected from damage in the event of a short circuit or breakdown of the test unit.
10. It includes standard capacitors and a high-voltage power supply for convenient on-site testing and reduced wiring.
11. The instrument uses a large-screen LCD display and is easy to operate. Comes with English programs.
