AC transformer ratio tester is an innovative product are mainly applied to change than group test transformer, PT and CT polarity test, test speed, high accuracy.
Technical Indicators
Working power supply
AC22050/60 HZ
Instrument weight
3.8 kg
Instrument dimension
325 mm L 225 mm W 125 mm H
Use of temperature
-10 50
Relative humidity
90 No dew
Functional Characteristics
It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage.
Based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is wider
Wide range and high accuracy, the variable ratio measurement range can reach 10,000, and the test accuracy can be guaranteed 0.3% when the maximum value is 10,000.
It has perfect protection functions such as reverse connection protection and output short circuit protection.

The TKJF-208 hand-held partial discharge detector is used to detect the local discharge power supply in medium and high voltage equipment.If no discharge is detected it does not mean that there is no discharge activity in medium and high voltage equipment.Power discharges often have an incubation period and the insulation may fail for reasons other than partial discharge.If a significant discharge is detected in equipment connected to the medium-high voltage power system the equipment maintenance department should be notified immediately.
