SUWI Series is designed using advanced engineering technology to test power and control equipment in the substations. SUWI is an all-in-one device that can test Relay Timing, Transformer’s Turns Ratio, Circuit Breaker Contact Resistance & Timing, Fuses, etc. SUWI is a combined substation testing device with advanced features; hence, named Substation Wizard which is SUWI. SUWI has easy, fast and accurate measurement features using its user-friendly software.
RELAY TIMING MEASUREMENT
SUWI can automatically test over-current, over-voltage, directional overcurrent relays and frequency control relays. SUWI has a current output of up to 110A AC/150A DC and a voltage output of up to 150V AC/ 220V DC. It has four universal input modules.
TURNS RATIO MEASUREMENT
By using ANSI/IEEE C57.12.90 measurement method, SUWI can produce precise results. SUWI is one of the most accurate devices with its wide range (0.8 to 33,000) ratio measurement capability and high precision (0.08 %). SUWI can also measure phase angle and polarity, apart from the ratio measurement. It has 1V, 4V, 10V, 40V and 100V AC test voltages generation capability. SUWI Series can measure the turns ratio of current, voltage and power transformers.
LOW RESISTANCE MEASUREMENT/MICRO-OHMMETER
SUWI can easily measure contact resistances of a circuit breaker, shunt, and disconnector by applying adjustable current up to 150A. It can calculate the real values of the resistors by providing penetration with the feature of the continuous current application. SUWI can measure resistance up to 5 Ω. It can measure the static resistance of the contact points of the circuit breaker. SUWI can measure idle circuit breakers as well as dual-grounded circuit breakers. The frequently used test models can be saved as templates and can perform the tests more rapidly and quickly.
CIRCUIT BREAKER TIMING
Contact Timing Tests are performed to determine the optimal performance of the breakers. Contact timing tests are performed to compare the breakers’ contact performance against the manufactures specifications. The breakers OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN and OPEN-CLOSE-OPEN operations are timed in milliseconds (ms) and cycles and then compared with the manufacturers’ specifications to determine the performance of the circuit breaker. SUWI can perform a 3-phase circuit breaker timing test; open, close, open-close, close-open, open-close-open timings, coil current measurement as well as internal and external trigger operations.
GENERAL FEATURES
A 7-inch IPS 1024×600 pixel touch panel display allows SUWI Series to show all measurement results on a single screen. Users can record test results to the device’s 8GB internal memory or an external USB flash memory. With the HighTest Data Management Platform (DMP Software), users can analyse and manage measurement results using a PC. Multi-language capability and a user-friendly operation menu make it easy to control SUWI Series. SUWI Series is a light, compact and rugged device with the protection class IP67 (case closed).
