Transformer On Load Tap Changer Parameter Tester Tap Position Transition Time Analyzer
The ZSK-I On-Load Tap Changer Parameter Tester is a specialized instrument designed for comprehensive analysis of transformer on-load tap changers. As the only moving part connected to the transformer circuit, proper testing of on-load tap changers is essential for transformer maintenance and reliability.
This equipment meets the requirements specified in "Procedures for Handling and Preventive Tests for Electrical Equipment" for checking action sequences and switching times of on-load tap changers.
The ZSK-I tester provides precise measurement of:
- Transition waveforms
- Transition time
- Transient resistance values
- Three-phase synchronization
