The MTO106 transformer ohmmeter is an easy-to-use, line-operated instrument specifically designed for safe and accurate field measurement of winding resistance in smaller transmission and distribution transformers. It has dual channels with a wide measurement range and can accurately provide information about the vast majority of power transformers, reactors and instrument transformers. The test current can be manually set in five different ranges to fit transformers of various sizes.
TSX 303 is an accessory to TRAX that enables automatic testing of all phases and taps of a transformer with only one single connection of test leads. This eliminates the need for reconnections between tests and greatly reduces the time needed for the full measurement procedure. Safety is also improved as the number of trips up and down the ladder to transformer is reduced to only connection and disconnection of the bushing cables.
