Product Description
High-precision intelligent power tester for motor, pump industry
CN8902 Three-phase electrical parameter measuring instrument
The three-phase electrical parameter tester is suitable for the true RMS detection of three-phase voltage, current, power, power factor, frequency and other parameters in motors, pumps, transformers, electric power and other industries, and can be wired according to two wiring modes of three-phase three-wire system and three-phase four-wire system, and can also be used as a single-phase meter. The accuracy is 0.5 and 0.2 grades.
Tester measurement range and accuracy:
Instrument safety indicators:
1,Insulation resistance: The shell and power input are greater than 5MΩ between each other.
2,Withstand voltage: 1800V and 10mA leakage current for 2 seconds between the power input terminal and the shell.
3,Grounding: The power supply is grounded, and the resistance between the shells is less than 0.2Ω.
