TSB
Trip Saver Box
The TSB, or Trip Saver Box, is best suited for those situations where a bucket truck is required to connect test cables to transformer bushings for performing Winding resistance and transformer ratio tests. Usually this requires multiple trips on a bucket to connect/disconnect test cables when switching between test equipment. The TSB eliminates these unnecessary trips by providing a central connection hub where both Vanguard winding resistance meters and turn ratio meters can connect. This results in increased safety and significant time savings.
The TSB has no effect on the accuracy specifications of the connected instrument.
The TSB is compatible with all Vanguard 3-phase TTR instruments and TRM-203/403 winding resistance meters.
