Performance of the high voltage clamp ammeter configuration
The high-voltage clamp ammeter is specially designed for online testing of the current and leakage current of high-voltage lines, and for distinguishing the operation of zinc oxide lightning arresters. Testing high voltage current below 60Kv can be divided into practical and wireless transmission types as needed. All are equipped with 5 insulated poles, and when testing high-voltage lines, pay attention to protective safety.
High voltage clamp ammeter configuration performance; Composed of a dedicated high-voltage detector and a 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, insulated rods can be omitted and can also be used as high-precision low-voltage clamp leakage current meters and ammeters, accurately testing 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 material of the 5-section high-voltage insulation pole is lightweight, which is conducive to high-altitude operations. It has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, and scalability.
The clamp shaped meter host is connected to an insulation rod and can be used for leakage current of 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 facilitates the clamp to leave the tested line by pressing or exiting the insulation rod; Widely used in substations. Power plants. Industrial, mining and power testing stations, electrician maintenance and field testing, etc.
High voltage clamp ammeters 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 will not exceed 500uA in rainy weather. Therefore, the operating situation can be judged based on its leakage current situation. Under stable voltage conditions, if the leakage current is large, the lightning arrester may be affected by moisture oxidation or oxidation. Judging based on on-site testing.
