Product Introduction
MOEORW-WBW03 is an upgraded portable transformer power analyzer with stronger load capacity and wider measurement range. It can complete full-current load test for transformers below 100kVA and 1/3 rated current test for transformers below 250kVA. It integrates automatic calibration, vector display, data storage, on-site printing and harmonic analysis. The humanized operation interface and stable performance make it ideal for field and laboratory transformer testing.
