High Voltage Clamp-On Ammeter Configured Performance
High-voltage clamp-on ammeter is designed for on-line testing of high-voltage line current, leakage current, identification of zinc oxide lightning arrester operation. 60Kv below the test of high-voltage current, according to the need to be divided into practical and wireless transmission type. They are equipped with 5 insulated poles, and the test of high-voltage lines should pay attention to the protection and safety.
High-voltage clamp-on ammeter configuration performance; by the special high-voltage detector with high-voltage insulating rod composition; wireless type with wireless receiver, can branch line within 30 metres to receive the measured data. In the case of low voltage, you can not use the insulating rod, can also be used as a high-precision low-voltage clamp leakage ammeter, ammeter use, can accurately test the 0.01mA leakage current.
Clamp meter clamp head and host body design integration, to ensure the high accuracy and stability of uninterrupted high-voltage line detection. 5 sections of high-voltage insulating rod material is lightweight, conducive to high-altitude operation, with moisture-proof, high temperature resistance, impact resistance, resistance to bending, high insulation, retractable and other characteristics.
Clamp meter host connected to the insulating rod, can be used for 60KV under the high and low voltage line leakage current. Current online measurement, and the instrument has a peak hold, data storage, wireless transmission and other functions, special high-voltage clamp meter by pressing or exit the insulating rod to facilitate the jaws away from the measured line; widely used in substations. Power plant. Industrial and mining and power testing stations, electrician maintenance and field testing.
High-voltage clamp-on ammeter can also do zinc oxide surge arrester and high and low voltage transformer ratio test use, need to pay attention to: surge arrester test leakage current is too small, the rain will not be greater than 500uA, so according to its leakage current to identify the operating conditions, in the case of voltage stability, leakage current is too large, then the surge arrester may be oxidised by moisture, or oxidation. According to the field test situation to judge.
