How to maintain a high-voltage clamp ammeter
As a tool for detecting and discriminating parameter values in various situations, high-precision instrument maintenance is crucial. Due to the infrequent adaptation of detection instruments and meters, maintaining the instruments well, extending their service life, and ensuring accuracy and range are steps that users must pay attention to
Taking the high-voltage clamp ammeter as an example, it is equipped with a high-voltage clamp meter with a high-voltage insulation rod, and the wireless type comes with a wireless receiver. High voltage detectors belong to high-precision and high stability instruments. Due to its infrequent use, paying attention to maintenance has become an essential key step. How to maintain a high-voltage clamp ammeter?
1. Pay attention to safety. When the line voltage exceeds AC600V during use, insulated poles should be connected.
2. To avoid impact on the high-pressure clamp, the iron core at the clamp head should not be cleaned with corrosive agents or rough materials. Instead, a soft cloth (such as eyeglass cloth) should be used, dipped in a clean anti rust and dehumidifying lubricant (such as WD-40), and the instrument should be gently wiped.
3. If the battery runs out of battery, replace it before starting work. Pay attention to the polarity of the battery and do not use the instrument for a long time. Please remove the battery. To prevent battery leakage and corrosion of the clamp circuit board.
Attention: High voltage clamp ammeters are suitable for high voltage lines of 60kV and below. Practical and equipped with high insulation poles together.
The advantages of high-voltage clamp ammeters in detecting high-voltage lines
Supporting facilities for high-voltage line detection in the power system of the power bureau and power supply bureau. For high-voltage instruments used to detect current and leakage in high-voltage power lines, the ETCR9000 series high and low voltage clamp ammeter is recommended. It can detect test currents of 60 kV and below in high-voltage power supply systems, with a resolution of up to 0.01 mA. The 48mm large clamp is suitable for clamping the vast majority of insulated outer wires.
Advantages of high-voltage clamp ammeters in detecting high-voltage lines:
1. Suitable for high and low voltage detection of 60kV and below, bare conductors or busbars of 35kV and below
2. 48mm clamp shaped mouth, can be used for clamping and testing of most high-voltage wires
3. 99 sets of data storage, more convenient for on-site inspection and recording
4. B-type wireless transmission type with wireless receiver, wireless transmission up to 30m
