Product description
Product parameters
Features:
● It can automatically realize transformer measurement, and can automatically switch current and voltage load boxes without manual intervention switching;
● The instrument can reach level 1. At present, most of the calibrators on the market use the RC phase shift 90° method to achieve data measurement. This method is susceptible to the ambient temperature and power frequency. Once the above environment changes, the measurement data will be greatly affected.
● The dial indicator, ratio difference and angular difference are displayed in extra large fonts for user observation.
● It can test the impedance of the secondary load of the current transformer; it can measure the admittance of the secondary load of the voltage transformer.
