Configuration and Performance of High-Voltage Clamp Ammeters
The high-voltage clamp ammeter is designed for online testing of current and leakage current in high-voltage power lines, and for identifying the operation of zinc oxide lightning arresters. Test high voltage current below 60Kv, divided into practical and wireless transmission types according to needs. All are equipped with 5 insulation rods, and attention should be paid to protection and safety when testing high-voltage lines.
High voltage clamp ammeter configuration performance; Composed of a dedicated high-voltage detector and high-voltage insulation rod; The wireless type is equipped with a wireless receiver, which can receive the measured data within 30 meters of the branch line. In low voltage situations, insulation rods can be omitted and can also be used as high-precision low-voltage clamp leakage current meters and ammeters, which can accurately test 0.01mA leakage current.
The integrated design of the clamp head and the host body ensures high precision and stability in uninterrupted high-voltage line detection. The 5-section high-voltage insulation rod is made of lightweight material, which is conducive to high-altitude operations. It has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, and stretchability.
The clamp shaped meter is connected to an insulation rod and can be used for leakage current in high and low voltage lines below 60KV. The current is measured online, and the instrument has functions such as peak holding, data storage, and wireless transmission. The dedicated high-voltage clamp meter allows the clamp to easily leave the measured line by pressing or withdrawing the insulation rod; Widely used in substations. power plant. Industrial, mining, and power testing stations, electrical maintenance and field testing, etc.
High voltage clamp current meters can also be used for detecting the ratio of zinc oxide lightning arresters and high and low voltage transformers. It should be noted that the leakage current of the lightning arrester during testing is small, and it usually does not exceed 500uA in rain. Therefore, the operating condition can be judged based on its leakage current. If the leakage current is large under stable voltage, the lightning arrester may be affected by moisture or oxidation. Judging based on on-site testing results.
