INTRODUCTION
MEWOI1020 series H/L Voltage Clamp Leakage Current Meter break through the traditional structure, specially designed and manufactured for measuring high voltage current, the meter adopts CT technology and mask digital integration technology, the instrument composed of special clamp current meter and high voltage insulation rod, among theMEWOI1000B type ---wireless transmission of test data, equipped with wireless receivers, which can receive the tested data within 30M straight-line distance. If not use insulation rod, which can be used as high accuracy low voltage clamp current meter. MEWOI1020 series H/L Voltage Clamp Leakage Current Meter connect with insulation rod, which can use for high voltage line current measurement of the wire with insulation skin below 60KV or bare wire below 35KV, online current measurements, also with peak hold, data hold and data storage and so on others functions, the special clamp current meter convenient to clamp or withdraw the tested wire operate by push or pull back the insulation rod, save time and convenient. It is widely used in substations, power plants, and industrial and mining enterprises, inspection stations, electrical maintenance departments for current detection and electrical field operations. It also can replace the H/L voltage transformation ratio tester, which can measure the H/L voltage current of the primary circuit and the secondary circuit respectively, and then calculate the H/L voltage transformation ratio. The insulation rod is light, has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, scalable and so on. |
