WJJC type impulse voltage tester is based on TB/T 2653, GB/T22387, GB/T17627, GB/T16927, GB14048, GB7251, GB/T16935, IEC61730, GB4706, GB3048 and other standard requirements , an impulse voltage test instrument used for safety performance testing of charging piles, new energy vehicles, solar energy, low-voltage complete sets, low-voltage electrical appliances, high and low voltage switches, watt-hour meters, motors, wires and cables, leakage protectors and other products. It is a "3C" certification inspection equipment for low-voltage complete sets of enterprises. The equipment adopts high-speed single-chip microcomputer design, LCD display, and touch button design. It has the advantages of easy operation, stable and reliable performance, and high degree of automation.

The temperature rise test cart is a dedicated mobile test platform for temperature rise testing of electrical equipment (such as transformers, motors, reactors, etc.).

The reliable and effective connection of the grounding wire of power equipment is the fundamental guarantee to ensure the safe operation of maintenance personnel. The grounding wire is the connection between the power equipment and the ground network, and the primary task is to hang the grounding wire for power outage maintenance. Therefore, in the "Twenty-five Key Requirements for Preventing Major Accidents in Power Production", it is clearly stated that the conduction inspection of the down conductor of the grounding device should be carried out once a year. This grounding down conduction tester is a portable tester with a high degree of automation developed by our company, which is used to ensure the good conductivity of the ground wire for power outage maintenance in the substation. The instrument is controlled by a high-performance microcontroller, which can realize the intelligent testing process.
