Brief Introduction
The HV transformer is an Oil-immersed single-phase transformer. This device is especially suitable for power systems, mining enterprises, scientific and research department to have insulation strength test under power frequency for all kinds of high-voltage electrical instrument, electrical components, and insulation materials. It is fundamental in high-voltage test.
Product Characteristics
1. High voltage test transformer has good material selection, reliable quality and good stability
2. Large voltage margin, small corona sound and local discharge
3. New insulating material, small size and light weight
4. Intuitive reading: this instrument uses digital LCD meter, can directly display the HV transformer’s outputting voltage and the control box’s outputting current value, easy to observe and record.
5. Fast protection: Over current protection using mechanical relays, this protection is reliable and fast.
6. Timing alarm: when the setting time is up, the alarm sends out acousto-optic signal, prompting the operator to reduce voltage as soon as possible.
