PEC-H07 Integrated Current Voltage Transformer Error Tester
PEC-H07 Integrated Current Voltage Transformer Error Tester
Product details
● This machine adopts the principle of small signal measurement, and a single instrument can complete the error testing of current and voltage transformers, making it convenient for on-site calibration of measuring devices.
● Use a power supply with a frequency close to the power frequency for testing to prevent interference.
● Wide measurement range.
● Directly integrate on-site data and determine whether it is qualified or unqualified.
● One measurement and display of the actual regulation point and error (angle difference, ratio difference) of the current and voltage transformer under any load.
● Measuring voltage transformers that meet the requirements of national regulations20％-120%Detection of point errors (angle difference, ratio difference) in the regulations.
● Detect the transformation ratio and polarity of the voltage transformer.
● Intelligent judgment of external wiring status, indicating wiring errors, transformation ratios, polarity errors, etc.
● It can store and print various measurement data on site, making it convenient for users to query.
● The instrument passes the standardUSBThe interface facilitates the connection and transmission of data with computers.
