Electric Leakage Tracking IEC Test Equipment IEC60695 EC60112 Standard of PLC Control
Product information:
KingPo has designed a series of PLC control with 7 inch touch screen display system test equipment, they are more humanized than the old version ones, and the new version PLC ones have won high reputation from the markets.
The automatic tracking leakage tester is designed and manufactured according to the standard requirements of IEC60112,IEC60335-1,IEC60598-1,UL746A and ASTM D3638-92 and etc..
Working principle :
The leakage tracking test(tracking index testing) is that the conducting liquid (0.1%NH 4 CL) of required volume in the required height (35mm ) and required time (30s) drops with the voltage between the platinum electrodes(2mm × 5mm )on the surface of solid insulating material. Thus the users evaluate the tracking resistance performance of solid insulating material surface under the combined influence of electric field and humid or contaminate medium. In a word, this device is used to measure the compare tracking index (CTI) and electrical resistance index (PTI).
Features:
The test device has a PLC control system and 7 inch color touch screen display system. A gauge block is supplied with the instrument to ensure the electrodes have the proper distance between them. The table height is easily adjustable to ensure the proper angle of the electrodes and height of drops. The rest of the test is controlled from outside the test chamber with the door closed. The voltage, limiting current, drip rate and number of drips are all set on the control panel. An operator should observe the test to see if a flame ignites. The instrument sounds an alarm if there is a tracking failure of at least two seconds.
