Product Description

This electrical tester's functional testing device is developed in accordance with the requirements of the National Power Corporation's notice on issuing the "Preventive Test Regulations for Electrical Safety Tools" (Trial) (State Power Corp. [2002] No. 777), and all product specifications meet national standards. The tester can be tested for functionality according to the "Preventive Test Regulations for Electrical Safety Tools." The product is suitable for testing electrical testers in all power-related industries from 10KV to 500KV. Specific requirements for functional testing refer to the DL740-2014 standard.

Product Features

In accordance with the DL740-2014 standard, the equalizing ring diameter for 10KV to 35KV is 550mm, with the center of the ring to the ground not less than 1.5m, and the equalizing sphere diameter is 60mm. For 66KV to 330KV, the equalizing ring diameter is 1050mm, the center of the ring to the ground is not less than 2.5m, and the equalizing sphere diameter is 100mm. This complete set of equipment is divided into 2 units.

For 10KV to 35KV voltage tester testing, a device with a uniform pressure ring diameter of 550mm is used. For 35KV to 500KV voltage tester testing, a device with a uniform pressure ring diameter of 1050mm is employed.

The voltage tester comes in two types: one with an extended contact electrode and another without. The testing methods for these two voltage testers are also different.

The tester's functionality testing includes the startup detection, same-direction interference detection, and reverse interference detection. The startup voltage alarm is considered合格 if it is between 15% to 40% of the nominal value; otherwise, the tester is deemed不合格.
