First, the main function 
 ? Ground fault point locating 
 ? Insulation condition of measuring equipment, insulation damage, resistance dropped to the requirements under the insulated grounding Find, locate insulation defects, in order to be processed. 
 ? System consists of: insulated grounding analyzer mainframe clamp receiver 
 ? Basic principle: signal generator, the measured object and the ground fault current, between the launch of a 1Hz ~ 500Hz low frequency voltage signal to produce a leakage current at the point of failure. Receiver fault current, depending on the size of the fault is displayed on the LCD. 
 ? Insulation test function: measurable, recording equipment, insulating state 
 ? State management functions: with the computer data processing, equipment insulating state can be described by the curve, the insulating state of the device dynamic tracking. Timely detection of insulation defects, and forecasting equipment insulation life. 

 Second, the main features of 
 ? Set the insulation test and the point of failure to find one. 
 ? Both can be set to multi-frequency, multi-voltage signal generator, in order to field test. 
 ? Easy to use, the device does not power outage, not rejection line, puzzled line to achieve the function. 
 ? Software (including the instrument software and management systems) can be personalized according to customer requirements. 
 ? Insulating state test analysis, trend analysis and status tracking. 
 ? Not only has the insulation resistance test, also has a recovery voltage, the absorption coefficient measurements, in order to accurately reflect the equipment insulation aging status. 
 ? Positioning signal frequency is low, only 1Hz, to eliminate the capacitive grounding a false impression. 
 ? High precision of the receiver be able to accurately locate the fault. 
 ? Clamp receiver of a variety of models to choose from.
