Feature:

• Significantly reduced power supply capacity requirements.
• Substantially diminished equipment weight and volume.
• Improved output voltage waveform.
• Prevents large short-circuit currents from burning the fault point.
• No recovery overvoltage occurs.

Advantage:

The unit incorporates protection functions against overvoltage, overcurrent, zero-position start-up, system detuning, and high-voltage flashover faults.

The entire unit is lightweight, facilitating on-site deployment.

The unit offers four operational modes, enabling flexible selection based on site conditions to enhance testing efficiency. Modes include: Fully Automatic Mode, Manual Mode, and Automatic Tuning with Manual Voltage Increase Mode.

Capable of storing, printing on-site, and remote printing of data.

Utilises DSP platform technology, facilitating easy functional expansion, reduction, and upgrades according to user requirements.
