TP673 dielectric loss and volume resistivity tester Introduction
TP673 dielectric loss and volume resistivity tester is widely used in power, petroleum, chemical and other industries, and is used in high voltage electrical equipment such as transformers, oil circuit breakers, oil-filled cables, power capacitors and oil bushings. In operation, due to the effects of oxygen, high temperature, high humidity, sunlight, strong electric fields and impurities, the performance of the insulating oil will gradually deteriorate, making it unable to fully play the role of insulation, and relevant tests must be performed on the insulating oil on a regular basis. In order to determine whether its performance has deteriorated, the quality of the insulating oil is closely related to the breakdown voltage. Features
Medium frequency induction heating, room temperature heating to temperature control (90 ℃) and constant temperature automatic measurement only 15 minutes
Simultaneous measurement of oil dielectric loss and volume resistivity or optional
Large-screen LCD display, just follow the Chinese menu prompts and enter the instructions, the instrument can work automatically
With communication function, can be configured with computer for real-time monitoring, dynamic observation of oil dielectric loss value changes with oil temperature and graphing
