ETCR9220B Wireless H/L Voltage Clamp Leakage Current Meter

Product Main Function

1. Measurement of H/L voltage AC leakage current (above 600V operate with insulation rod)

2. Range : AC   0.00mA~60.0A

3. Resolution : 0.01mA

4. Data Storage : 99 groups

5. Line Voltage : Test of the wire with insulation skin below 60kV, test of  bare wire below 35kV (operate with insulation rod)

6. CT Size :φ68mm

    ETCR9220B Wireless H/L Voltage Clamp Leakage Current Meter  adopts CT  technology and mask digital integration technology, the instrument composed of special clamp current meter and  high voltage insulation rod, wireless transmit test data,equiped with wireless receiver which can receive the tested data within straight line distance 30M. If not use  insulation rod, which can be used as high accuracy low voltage clamp current meter. 

   ETCR9220B 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.
