T-213S Three Phase Transformer Dc Resistance Test Equipment
T-213S three phase transformer dc resistance test equipment with three channel functions can test transformer, mutual inductor, reactor, dc resistance of motor and perceptual load. This transformer DC resistance tester adopts microprocessor technology and four wire method for testing, small in size, light weight, strong function, easy operation, Designed for production test and field measurement field staff. Large screen LCD in English and Chinese, especially suitable for continuous the points contact load switch does not block the test, dynamic measurement process, give an automatic arc suppression instructions alarm, can edit the user information, test records can save and print. It can be configured PC online communication and testing capabilities. It is also as automatic transformer demagnetization tester.
