With over 50 years of relay testing experience, the SR-98 incorporates the latest in Digital Signal Processor (DSP) and microprocessor-based technology to provide a powerful, easy to use relay test set.
The SR-98 is a multipurpose, light weight, field portable test set capable of testing a wide variety of electromechanical, solid-state and microprocessor based protective relays. ?captures test current and high-speed trip operation of single-pole, small molded case circuit breakers, motor overload relays and similar protective devices.
The SR-98 incorporates a large, easy to read, even in direct sunlight, LCD display, which shows AC and DC Amperes, AC and DC Volts, and Time in both Seconds and Cycles. Depending on the type of test selected, other values may be displayed, such as Ohms, Watts, VARS, Phase Angle, Frequency or Power Factor. Metered quantities such as AC Amperes, AC Volts, DC Volts or DC Amperes, and Time are simultaneously displayed on the screen. The read-and-hold metering feature provides a fast and accurate preset of test values
The SR-98 can test a wide selection of relay types. Its advanced phase shift capability allows the unit to continuously adjust the phase angle relationship between the voltage and current outputs. Therefore, values like reach, maximum angle of torque, directional balance points, and closing angles can be easily tested. In addition, breaker contact simulation provides swift and easy testing of reclosing type relays.
