SAT40A II series Coil Analyzers - Beijing Kanggaote Instruments and Equipment

Product introduction

The Coil Analyzer SAT40A II series is a powerful and lightweight (only 11 kg / 24.3 lbs) tool for testing circuit breakers where a substation battery is not available. It is a unique device in the market due to its dual purpose. SAT40A II Series as a Power Supply for Coils and Spring-Charging Motors SAT40A can be used as a DC and AC power supply unit for circuit breakers during commissioning and regular maintenance testing. The typical application covers scenarios when substation battery is not connected or available. An advantage over substation battery is enabled testing in under-voltage and over-voltage conditions. Furthermore, the stable voltage outputs enable an analysis of the coil and motor current graphs recorded with circuit breaker analyzers.

▪ Lightweight – only 11 kg / 24.3 lbs
▪ Powerful AC & DC motor outputs – up to 40 A
▪ Separate opening and closing coil outputs:10 V – 300 V DC, 10 V – 250 V AC
▪ Coil current and resistance measurement
▪ Minimum trip voltage test (fully automatic)
▪ Temperature sensor input
▪ DV Win software

The Coil Analyzer SAT40A II series is primarily designed for LV, MV and HV circuit
breakers testing during manufacturing, commissioning and maintenance stages.
The testing process may encompass any or all of the following:
▪ Power supply for coils and motor while testing with circuit breaker analyzers from
different vendors:
- AC/DC power supply for circuit breaker breaking and closing coils actuation
- AC/DC voltage for supplying the spring-charging motors
▪ Full range testing of circuit breakers with CAT & SAT test system (joint software for test
preparation, control and reporting).
▪ Coils resistance measurement as per IEC 62271-100
▪ Coils current value measurement
▪ Minimum trip voltage-test of the circuit breaker's coils (IEC 56, ANSI C37.09).
▪ Motor current and operating mechanism charging time (IEC 62271-100)
▪ Temperature rise test of the auxiliary and control equipment

Coil Analyzer SAT40A II series can be used in factories and laboratories, but also in high induction switchyards, power and industrial environments.

The motor outputs on SAT can also be used as a general power supply unit or a temporary
battery charger.
