Product Introduction
Because the insulation layer of the cable capacitance is large, the frequency dielectric loss instrument can not meet the test requirements. Ultra-low frequency because of the low working frequency, so the carrying capacity is strong, suitable for cable dielectric loss test.
Dielectric loss ultra-low frequency is a multi-function cable tester, It can measure dielectric loss, capacitance, and insulation of cable, and also do voltage tests. Due to the sampling device of dielectric loss-related electric parameters in the ultra-low frequency booster and control box, the device is small in size, light in weight, simple in connection, and easy to use,it is the cable field test, judging the cable insulation performance of good assistant.

Product Feature And Application
1. Very low frequency with rated voltage less than or equal to 50kV adopts single link structure (one booster), very low frequency greater than 50kV adopts series structure (two booster in series). The overall weight is greatly reduced, the load capacity is enhanced, and the two booster can be used separately to achieve a multi-purpose machine.
2. Current and voltage data are sampled directly from the high-voltage side, so the data is accurate.
3. Intelligent comprehensive protection function: no need to set the current and voltage protection value. The instrument can calculate the overvoltage and overcurrent protection value according to the capacitance of the test product and the test voltage value. It also protects against sudden changes in voltage and current, so it can capture the discharge. The protective action time is not more than 20ms.
4. 150kv high voltage line output, safe and reliable.
5. Because of the closed-loop negative feedback control circuit, the output has no capacity rise effect.
6. The new product adds the dielectric loss measurement function, which can simultaneously measure the dielectric loss, capacitance and insulation resistance of the test product.
