Product description： 120KV 10ma DC Cable Test System is an important equipment for DC voltage withstand test and leakage current test of HV electrical equipments, cables, surge arresters in electriv industry and power supply departments. 120KV 10ma DC Cable Test System is developed based on the calibration made by National HV Meterage Station, it accords with the standard "Generation Requirement of Portable HVDC Generator"(ZGF 24003-90) Technique Index： 1. power: AC220V+10%, 50Hz+1% 2. Output voltage indicator accuracy: <1% 3. Output current indicator accuracy: <1% 4. Ripple contain factor: <0.5% 5. 0.75 times output voltage indicator accuracy: <1%, can be locked 120KV 10ma DC Cable Test System 1 rating output DC voltage（kV） rating output DC current（mA） rating output power（W） doubler reticfier case height（m） weight（kg） ZGF-120 120 10 1200 0.8 20 Advantage： The new technology, new material and optimal selected components are applied, It has the advantages of high power, small volume, light weight, good performance and high stability. Features： 1. High reliabiliy: high frequency voltage multi-doubler reticfier, simple circuit 2. Small volume: one person can carry the largest HVDC generator (200kV/2mA). Its volume is only 1/(2～5) as the volume of the same kind of equipment made in Japan. 3. Perfect seal by metal housing, high mechnical stength. Irs performence will not be influenced by viberation, moisture, dust and meterological condition. 4. Safe, convenience in operation, metal housing grounded. built-in HV terminals. 5. There is no high voltage and low voltage connecter outside, easy connection. 6. Good auto protection function. It can nor be switched on if the HV output knob is not at zero position. Poeration is simplw. It will not cause maloperation and automatically switch off in over voltage and overcurrent case. There is dampong resistor indide.It is not necessary to connect damping resistor outside. 7. Excellent accuracy: The leakage current at HV side is meadured by digital meter accuracy: 1uA, range switch is not required, disvharge withstand current measurement function is available at low voltage side, It use precise resistor with good stability to measure high voltage.
