DC Hipot Tester, High Voltage Direct Current Generator for Power Cable and Arrester Test

GDF DC Hipot Tester,High Voltage Direct Current Generator for Power Cable and Arrester Test

Introduction:

• GDF Series DC Hipot Tester,High Voltage Direct Current Generator is an important equipment for DC voltage withstand test and leakage current test of HV electrical equipment, cables, surge arresters in electriv industry and power supply departments;

• GDF Series DC Hipot Tester,High Voltage Direct Current Generator is developed based on the calibration made by National HV Meterage Station, it accords with the standard "Generation Requirement of Portable DC HV Generator"(GDF 24003-90);

• 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;

Specifications:

• Power: AC220V+10%, 50Hz+1%;

• Output voltage indicator accuracy:<1%;

• Output current indicator accuracy:<1%;

• Ripple contain factor:<0.5%;

• 0.75 times output voltage indicator accuracy:<1%, can be locked;
   

Model Selection:

Features:

• High reliability: high frequency voltage multi-doubler rectifier, simple circuit, high overload capability, rare fault, without maintenance.

• Small volume: one person can carry the largest DC HV generator (200kV/2mA). Its volume is only 1/(2~5) as the volume of the same kind of equipment made in Japan. It reaches the advanced level in the world.

• Perfect seal by metal housing, high mechanical strength. Its performance will not be influenced by vibration, moisture, dust and meteorological condition.

• Safe, convenience in operation, metal housing grounded. built-in HV terminals.

• There is no high voltage and low voltage connect outside, easy connection.

• Good auto protection function. It can nor be switched on if the HV output knob is not at zero position. Operation is simply. It automatically switch off in over voltage and over current case. There is dam pong resistor inside.It is not necessary to connect damping resistor outside.

• Excellent accuracy: The leakage current at HV side is measured by digital meter accuracy: 1uA, range switch is not required, discharge withstand current measurement function is available at low voltage side, It use precise resistor with good stability to measure high voltage.

High precision double side surface grinding or fine grinding is a super finishing process performed by removing material from two surfaces of a component resulting in extremely precise geometric accuracy and surface finish. Typically, it is the last grinding step of a mechanical production chain utilized to improve and/or correct the geometry of parts coming from sintering, sawing, molding or similar operations. Depending on the application, the stock removal also can be taken from just one surface.
