HighTest SUWI-120 Multifunction Substation Test Set

HighTest SUWI-120 Multifunction Substation Test Set

HIGHLIGHTS

SUWI-120 series stands as a versatile testing instrument meticulously crafted to evaluate the performance of power and control apparatus within substations. It encompasses an array of essential tests, including the precise assessment of Relay Timing, the determination of a Transformer’s Turns Ratio, the scrutiny of Circuit Breaker Contact Resistance and Timing, as well as the examination of MCBs, among other critical functions. This all-encompassing substation testing device has earned the name SUWI, from our belief in its skills as a Substation Wizard.

RELAY TIMING MEASUREMENT

The SUWI instrument can automatically test over-current, over-voltage, directional overcurrent relays and frequency control relays. SUWI has an adjustable output current up to 110A AC / 120A DC and an adjustable output voltage to 150V AC / 220V DC. It has four universal input modules.

TURNS RATIO MEASUREMENT

Employing elements of performance tests specified in the ANSI/IEEE C57.12.90 standard, the instrument performs transformer ratio measurements to a precision of 0.08 % across a ratio range of 0.8 to 10,000. SUWI also measures phase angle and polarity, and it can generate 1V, 4V, 10V, 40V and 100V AC test voltages to facilitate the measurement of turns ratio for current, voltage and power transformers.

CONTACT RESISTANCE / LOW RESISTANCE MEASUREMENT

SUWI has an adjustable output DC current up to 120 Amps which facilitates the measurement of contact resistance of a circuit breaker, a shunt or disconnector. SUWI-120 can measure resistance up to 5 Ω, with a resolution of 0.01μΩ.

CIRCUIT BREAKER TIMING

Contact Timing Tests are performed to determine a breaker’s contact performance against its manufactured specifications. The timing for a breaker’s operation such as OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN and OPEN-CLOSE-OPEN are measured for all three-phases simultaneously. SUWI can perform 3-phase circuit breaker timing test cycles as described above along with coil current measurements using internal and external trigger inputs.
