KP-8 Handheld Transformation Ratio Group Automatic Tester

Estimated delivery : 30 Days; MOQ : 1 PCS
Features :

1. Three-phase constant voltage power supply (coefficient line voltage 180)
2. During the measurement process, the range can be automatically switched according to the size of the measured data.
3. Automatic measurement
   The transformation ratios and groups of each phase of a three-phase transformer can be automatically tested at one time as needed.
4. Automatic correction
   An external standard transformer can be connected to automatically calibrate the accuracy of the instrument.
5. Automatic protection
   In case of wrong connection or external short circuit, the power supply can be automatically cut off and the alarm will be sounded.
6. Computer connection
   Provide users with RS232 or RS485 communication interface according to their needs, and transmit data to the host computer for computer management.
