Product Description

HV-GF10 DC System earth fault detector 


Ⅰ Product overview

HV-GF10 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%.


Ⅱ Products features

1. Easy to use, customers can directly operate only need turn on the power switch.

2. Safe and reliable, do not need power off the charger or other power source, without effects to DC system.

3. Applies to various voltage class, DC system 220V, 110V, 48V, 24V.

4. Wide range of application, any power plant, transformer substation, colliery, chemical plant and others power supply departments.

5.Easy to carry, the signal receiver equipped with battery, do not need external power source.

6.DC system do not need power off when searching the earthing contact, do not affect the normal work of the system.

7. Strong anti-jamming ability, without the effects by system distributed capacitance.

8.Intelligent charge Management, shorten the charging time, lengthen the battery life.
