Product Introduction
The oil dielectric strength tester is a professional device used to test the electrical properties of insulating oil. The tester uses advanced technologies such as central processing units and large-scale integrated circuits to achieve fully automated testing. Its working principle is to gradually increase the voltage until the insulating oil breaks down, and record the breakdown voltage to evaluate the dielectric strength of the oil.
Product Features
High Precision
The oil dielectric strength tester uses advanced signal acquisition and processing technology, combined with precision sensors, to achieve a measurement accuracy of ±2%, which can accurately reflect the true dielectric properties of oil.
Stability
The oil dielectric strength tester is equipped with a stable power supply system. Under a voltage fluctuation of ±10%, the output voltage fluctuation is controlled within ±0.5%.
