• Digital display meters mounted on the panel.

• Monitoring HV side voltage, HV side current, LV side current and indicator of zero, power, working start, timing.

• Over-current protection, zero-starting protection, sound, and light alarm.

• With new type time relay, time range is wider (1S ~ 99H).

• Using the latest current relay, more accurate and reliable.

•The high-voltage coil of the test transformer is a multi-layered cylindrical tower type, wound with high-quality polyester enameled wire and high-voltage-resistant insulation material, featuring light weight, small size, easy mobility, and superior performance.

• The test transformer is equipped with swivel casters and a tie rod for easy movement and handling.

• The test transformer adopts an integrated AC/DC design, simplifying wiring and enabling flexible operation. •
