Handheld zinc oxide lightning arrester live tester manufacturer

Product Overview
Zinc oxide lightning arrester is an important protective equipment for power supply lines and equipment. If the lightning arrester in the power system ages, is damaged or fails, it may cause large-scale power accidents, resulting in damage to power equipment and power outages in power supply lines. Therefore, regular testing of zinc oxide lightning arresters in power lines can effectively eliminate potential safety hazards, ensure the safe operation of the power system, and improve the quality of power supply.
TPYBL-SCHandheld zinc oxide lightning arrester live tester manufacturerThe new ultra portable zinc oxide lightning arrester live tester developed by Topu Company is used to analyze the full current of zinc oxide lightning arrester (MOA). The main purpose is to measure the resistive current of MOA and determine its degree of moisture and aging. This instrument can be used for on-site live measurement tests, as well as for MOA acceptance and factory testing.
Operation instructions
1. Wiring diagram for live test of zinc oxide lightning arrester (recommended for use).

2. Wiring diagram for non electrified test of zinc oxide lightning arrester (recommended for use).

Explanation: According to different voltage levels, the voltage applied to the lightning arrester is generated by the boosting test transformer.
2) The voltage signal is taken from the low voltage side of the test transformer, and its voltage value must not exceed 250V. At this time, the instrument can customize the voltage level of the primary and secondary sides according to the transformation ratio of the test transformer, so as to measure the true voltage value applied to the lightning arrester.
3) Connect a 200 Ω -500 Ω resistor (1/4W or more) to the end of the lightning arrester and ground it (as shown in the diagram). The current signal is taken from both ends of the resistor. The internal resistance of the instrument current channel is approximately zero to ensure that all current flows through the instrument during testing. No resistance is required, but A-phase testing must be selected.
3. When the instrument is connected to the test line as required, turn on the power switch, and the LCD displays the main menu.
