Coil Analyzer SAT30A Brochure SAT30A Print this page Lightweight - only 9 kg Coil resistance measurement Coil current measurement Minimum trip voltage test Powerful - up to 30 A Voltage 10 V to 300 V DC Voltage 10 V to 250 V AC Fully automatic operation Powerful breaker coils analyzer Description Coil Analyzer SAT30A is a powerful instrument ideal for testing of circuit breakers, where substation battery is not connected or available. The SAT30A is intended to operate breaker coils, and spring charging motors as a part of commissioning and maintenance testing. SAT30A measures current and resistance of circuit breaker coils. SAT30A can also be used to test minimum trip voltage of circuit breaker coils, as well as under voltage releases of circuit breaker. Output voltage is selectable from 10 V to 300 V DC or from 10 V to 250 V AC. The SAT30A is powerful and versatile unit, with possibility to generate at 230V mains supply initial current of 30 A as well as continuous current according to the tables below: Mains voltage Load voltage Max Current Max load interval 230 V 110 V DC 24 A 20 A 10 A 20 sec 60 sec continuous 220 V DC 12 A 10 A 7 A 20 sec 60 sec continuous 115 V 110 V DC 12 A 10 A 7 A 20 sec 60 sec continuous 220 V DC 7 A 6 A 5 A 20 sec 60 sec continuous Mains voltage Load voltage Max Current Max load interval 230 V 110 V AC 10 A 5 A 1 sec continuous 220 V AC 10 A 5 A 1 sec continuous 115 V 110 V AC 10 A 5 A 1 sec continuous 220 V AC 10 A 5 A 1 sec continuous The set is equipped with thermal and over current protection. SAT30A is easy to use and has accessory cable-set with touch-proof contacts. The SAT30A has very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing proprietary hardware and software. Applications SAT30A is developed for use in switchyards, electric power and industrial environment. An important part of commissioning and maintenance testing is a circuit breaker testing. SAT30A is used for: operating circuit breakers supplying spring-charging motors coils resistance measurement coils current measurement minimum trip voltage-test of the circuit breaker's coils undervoltage release test power supply at test with breaker analyzers Many other important parameters are possible to test with a breaker analyzer. SAT30A is also used as a power supply unit. It is compatible with breaker analyzers from different vendors. SAT30A can also be used as general power supply unit or temporary battery charger. Coil resistance measurement as a unique option on all coil testers Experience from field testing of circuit breakers show that, measurement of coil resistance is very important task for circuit breaker monitoring. This feature makes Coil Analyzer SAT30A as one of most versatile and useful devices for Circuit Breaker coil analysis on market. Automatic testing of the minimum trip voltage of a breaker To ensure that circuit breaker operation is guaranteed under the most onerous conditions placed on the substation tripping supply, circuit breaker trip coils are specified to work with a minimum tripping voltage much below the nominal battery voltage. SAT30A have built-in capability to perform automatic test of minimum trip voltage. The minimum trip voltage test is described in a number of international and national standards such as IEC 62271-100, ANSI C37.09 etc. Test of under voltage release Undervoltage releases are solenoids that actuate a tripping mechanism upon interruption of the voltage. When line power is too low, or absent the spring loaded solenoid releases and strikes the mechanical trigger, this in turn trips the breaker. One reason why Under Voltage breakers are used is to keep machinery from starting automatically when incoming power is restored after a power outage or after a significant drop in line voltage. SAT30 can perform automatic test of under voltage release by generating decreasing voltage signal. When the under voltage release is operated, the SAT30A will indicate voltage and current value.
