ATTRM-901P
Turns Ratio Tester
ATTRM-901P is applied to measure the voltage ratio of three phases or single phase transformer. All the data and test results are showed on a 320*240 LCD. All the test results could be printed by the micro printer or saved on the storage of the tester. The tester has good performance, auto protection and anti-disturbance features. The equipment excites the High Voltage winding of the test transformer and measures the output of low voltage winding in ratio metric circuit and display the result on LCD indicator.
