Description

The Coil Analyzer SAT40A II series is a powerful tool for testing circuit breakers where a substation battery is not available. It is unique device in the market due to its dual purpose: - It can be used as a stable power supply for coils and spring-charging motors (both DC and AC power supply voltage) during commissioning and maintenance testing. - It is powerful analysis tool for assessing conditions of circuit breaker auxiliary circuit and coils. The Coil Analyzer SAT40A II series has separate DC and AC coil outputs for power supply of opening and closing coils. The output voltage is selectable in the ranges from 10 V to 300 V DC or from 10 V to 250 V AC. The Coils outputs can withstand up to 15 A current. The DC and AC motor outputs can generate from 10 V to 300 V DC and 250 V AC voltage. The motor outputs can withstand starting (inrush) currents up to 40 A. These outputs can also be used as continuous power supply outputs.

The SAT40A II series is equipped with thermal and overcurrent protection. Thanks to a proprietary hardware and software design solution, it is capable to decrease influence of electrostatic and electromagnetic interference in HV electric fields. Communication between the SAT and a PC is through an USB (as standard) or an RS232 cable (as an option). Bluetooth communication interface is also available as an option. The SAT40A II series instrument can store internally up to 100 measurements. All measurements are time and date stamped. The SAT40A II series is easy to use and has accessory cable-set with touch-proof contacts. It can work as a standalone, as well as PC controlled unit (DV-Win software). The software enables use of SAT and CAT Circuit Breaker Analyzers & Timers as one test system (control and reporting done with the same software). The SAT40A II series can be used as a power supply unit with other vendor’s circuit breaker timers & analyzers also.

Applications 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 springcharging 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.

Using SAT as a power supply for coils and motor during switchgears testing

Coil Analyzer SAT40A II series can be used as a stable power supply for coils and springcharging motors (both DC and AC power supply voltage) during switchgears and circuit breakers testing. This application is significant in all situation when substation battery is not available.

SAT enables testing in under-voltage and overvoltage conditions, which is often required during circuit breaker testing. In addition, stable outputs enable analysis of the coil current graphs recorded with circuit breaker analyzers. SAT coil outputs are not intended for continuous voltage generating. SAT’s motor outputs capabilities are presented in the table below:
