Transformer On Load Tapchanger Analyzer
Product Introduction
Transformer on-load tap changer analyzer is a portable integrated testing device focusing on OLTC transition characteristic detection. With stable high current output and high precision measurement algorithm, it accurately measures transition resistance, switching interval and contact state. Compact body and intelligent APP operation greatly improve test efficiency, widely used in manufacturer delivery inspection and old equipment renovation assessment.
