CT PT load box Please use an appropriate power cord for this product. Only the power cord dedicated to the machine or a suitable gauge can be used. Connect and disconnect properly. Please do not connect or disconnect the test lead if it is connected to the charging terminal. Ground the machine. The grounding pole of the machine enclosure must be grounded, unless the product is grounded through the power ground wire. To avoid electric shock, the grounding conductor must be connected to the ground. Before connecting the input or output terminals, make sure that the machine is properly grounded.
Introduction 3 phase transformer on-load tap changer testeris mainly used to test three-phase transient time, transition waveform, transition resistance, synchronization state, etc. The transformer on-load switch tester is a comprehensive transformer on-load switch measurement and tester, which is used to measure and analyze the electrical performance indicators of power transformers and special transformers on-load tap-changers. The transformer on-load switch tester can automatically capture and display the transition resistance during the transition process. There is also a process of time jumping. Technical parameters Three phase constant current source charge,charge current: 3A/1A; 0.6A/0.2A Maximum voltage of the port: 24V Maximum range of transition resistance: 100 Measuring range: 1A 0.4 20 0.2A 10 100 Record time of waveform:300ms Sample rate: 30k Resolution of time:0.1ms Resolution of resistance: 0.1 Accuracy of transition resistance: ±5% Reading±0.1 Accuracy of transient time: ±0.5% Reading±0.2mS Temperature: -10-40 Humidity:
