1. Introduction
High and low voltage clamp ammeters are high-voltage measurement tools, which are composed of a special clamp ammeter and a high-voltage insulating rod. The clamp-type ammeter uses a mask integrated circuit to connect an insulating rod inside and is used to measure the current of the following high-voltage lines with insulated sheaths or bare wires. When the insulating rod is not used, it can also be used as a high-precision low-voltage clamp ammeter or leakage current meter, which can accurately distinguish the current or leakage current.
It is easy to use and easy to carry. Equipped with a telescopic insulating pole for easy portability and use. It uses high-precision technology to ensure high precision, high reliability and high stability of uninterrupted testing all year round.
The high and low voltage clamp ammeter also has the functions of peak hold, data holding, data storage and other functions. Its special clamp ammeter can easily clamp or evacuate the measured conductor by pushing forward or withdrawing the insulating rod, saving time and speed. It can be widely used Conduct current testing and field electrical work in substations, power plants, industrial and mining enterprises, testing stations, and electrician maintenance departments. Insulating rods are lightweight, moisture-proof, high temperature resistant, impact resistant, bending resistant, highly insulating and retractable.
