Insulation is one of the most important constituents of a transformer. Any weakness in the insulation may cause failure of transformer. To ensure the effectiveness of the insulation system of a transformer, it must confirms the dielectric test. But the power frequency withstand test alone can not be adequate to demonstrate the dielectric strength of a transformer.

1. The current, voltage and waveform data are directly obtained from the high voltage side, so the data is accurate.2. It has over-voltage protection function. When the output exceeds the set voltage limit, the instrument will stop for protection, and the action time is less than 20ms.3. It has over-current protection function: it is designed as high-voltage and low-voltage dual protection, and the high-voltage side can carry out accurate shutdown protection according to the set value; when the current on the low-voltage side exceeds the rated current, it will carry out shutdown protection, and the action time is less than 20ms.

Given the diverse functional requirements of the grid’s protection system, testing capabilities require a new level of sophisticated test hardware and software with which to analyse the entire protection system’s (or individual protection component’s) operation in "real life" situations. It is further necessary that these expanding testing capabilities be met with a similar improvement in the simplification of a test instrument’s user interface and software control.

High-voltage Dividers (High Potential Divider) are used to measure voltages and decouple partial discharges in high-voltage test systems. Depending on the specific type, they are used to measure alternating voltage (AC), direct voltage (DC), lightning impulse voltage (LI), and switching impulse voltage (SI) systems. High-voltage dividers by HIGHVOLT comply with the relevant IEC standards. The systems are available for both indoor and outdoor use.
