Product Overview
Section 1 : DRT-320L 20A Automated Six-winding Transformer Ohmmeter
Introduction
The DRT series of automated six-winding transformer ohmmeters delivers full eight-terminal resistance measurement capability. It's designed to save you time by testing all normal six windings without having to disconnect and reconnect leads during testing. Also, the simultaneous winding magnetization (SWM) method gives fast and reliable measurements, even on large transformers with delta configuration on the low voltage side.
