Product overview
PDF1000 DC System earth fault detector applies to all DC system in any voltage class, equipped with high-precision tester, expanded the tested range and strengthened the anti-interference ability by processing many kinds of signal. Adopted excellent method of calculation and advanced Fuzzy control calculation theory, show us the advancement of the measured circuit branch by numerical value, which reflect the superiority of artificial intelligence sufficiently. Correctly detect the position of the earthing contact each time.
The device with system security as paramount premise, according to the highest industry standards requirements, use reliable low-frequency signals to detect, and do a lot of practical applications in the field, without any impact on the system.
The device is used to find the DC system ground exact location of power plants and substations under power-on state. It can quickly find the earthing contact to various types of ground fault; the accuracy rate reaches 100%.
