    The Weschler Transformer Advantage is a precision temperature monitor for liquid immersed power & distribution transformers. It is rugged, fully electronic and field configurable.  With the Transformer Advantage, users can extend transformer life, utilize maximum capacity and reduce maintenance costs.

    Seven models offer a range of functions and configurations. All use an accurate and stable platinum temperature sensor (RTD) to precisely measure liquid temperatures.  Simulated winding models derive winding temperature from a heated thermowell.  Calculated winding models use a proprietary algorithm to compute winding temperature from oil temperature, winding current and transformer parameters entered during setup.

    The Transformer Advantage is a cost-effective upgrade from analog gauges and is suitable for use on new or existing transformers.  The rugged metal case can be mounted directly on the transformer or in the control cabinet.  Probe options fit most popular thermowells, or magnetically mount on units without wells.  This Weschler product has been field proven to provide years of trouble-free service.  A wide variety of options tailor the Advantage to each application.

  • Analog Switchboard Meters
    Weschler analog switchboard instruments display electrical and process signals. They fit standard ANSI panel cutouts and utilize proven Westinghouse designs for ultimate reliability. High shock & nuclear qualified models available....

    • Rugged Westinghouse designs – Made in USA
    • Switchboard & panel styles
    • High accuracy, full view construction
    • Taut band construction
    • High overload capacity
    • Meet ANSI STD C39.1
    • Military & nuclear versions

    Weschler analog meters are built in the USA using Westinghouse designs and tooling.  Edgewise meters are available in vertical and horizontal styles.  These 6” meters have a rugged taut-band movement for repeatability and long life.  Circular models can be ordered in the standard 4¼” or large 8¾” size for improved visibility.  Both include a metal case and wide viewing angle scale.

    Functions available include DCV, DCA, ACV, ACA, frequency, watts, vars, power factor and synchroscope. Custom scales are included on request.  High shock switchboard units meet the needs of military, marine and severe industrial applications.  Nuclear models are 1E safety rated for use in nuclear power plants.
