Analyze the working principle from the internal structure of the clamp-on ammeter
High-voltage line current testing, protective measures require strict, a good test of high-voltage lines is not only the accuracy of the product, resolution. Also have the best protective facilities. Good external insulation is also essential to protect personal safety. This is why all safe production sites.
High-voltage current testing equipment High-voltage clamp-on ammeters are available in two types: basic and wireless. The basic type consists of a high-voltage clamp meter and five insulated connecting rods; the wireless high-voltage clamp meter consists of a high-voltage clamp meter, a wireless receiver, and insulated rods. Each clamp meter is equipped with an insulating rod, its special clamp ammeter by pressing or retreating from the pull back insulating rod can be convenient clamp or evacuation of the wire under test. Pull away and test wire distance, to protect personal safety. If you do not use the insulating rod, can also be used as a high-precision low-voltage clamp ammeter, leakage ammeter.
Dangerous lines, test carefully, due to high-voltage lines are very dangerous, the operator must be strictly trained and obtain the relevant national high-voltage operation certification to carry out on-site testing. High and low voltage clamp-on ammeter Connected to the insulated pole, it can be used for high voltage line current measurement below 60kV, online current measurement, and also has the functions of peak hold, data hold, data storage, wireless transmission, etc. It can also replace the high and low voltage ratio tester, i.e., measure the high and low voltage current of the primary circuit and the secondary circuit respectively, and then calculate to get the high and low voltage ratio. Insulation pole lightweight, with moisture, high temperature, impact resistance, bending resistance, high insulation, scalable and so on.
