JKDL- ⅰ JKDL- ⅲ short circuit impedance tester

The JKDL-I/JKDL-III short-circuit impedance tester is used for testing parameters such as transformer short-circuit impedance. The short-circuit impedance method is a traditional method for determining winding deformation. According to GB1094.5-2003 and IEC60076-5:2000 regulations, the change in short-circuit reactance is an important basis for determining whether the transformer winding is deformed. It has two models: single-phase measurement (JKDL-I) and three-phase measurement (JKDL-III).
Main functions and features:
1. Measure parameters such as transformer short-circuit impedance, short-circuit reactance, three-phase impedance voltage, etc.
2. The screen displays parameters such as voltage, current, power, frequency, etc. for testing.
3. Measurement can be completed using only a single-phase 220V AC power supply.
4. The wiring operation is simple and convenient, with one wiring and automatic three-phase measurement upon startup.
5. Large screen color LCD with clear and concise display.
6. It has the function of storing test data and printing test results.
