ETCR 9220 H/L Voltage Clamp Current Meter - ETCR

ETCR 9220 H/L Voltage Clamp Current Meter

Product Main Function

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

2. Range : 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






      ETCR 9220 H/L Voltage Clamp Current Meter adopts CT  technology and mask digital integration technology, the instrument composed of special clamp current meter and  high voltage insulation rod, If not use  insulation rod, which can be used as high accuracy low voltage clamp current meter.

      ETCR 9220 H/L Voltage Clamp Current Meter connect with insulation rod, which can use for hight 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 function, the special clamp current meter convenient to clamp or withdraw the tested wire operate by push or pull back the insulation rod.It is widely used in substations, power plants, industrial and mining enterprises, inspection stations, electrical maintenance departments for current detection and electrical field operations. It 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 handiness, and has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, scalable and so on.
