CBCT

Circuit Breaker Coil Tester

  
       
View Full Specs

The CBCT is a variable voltage DC power supply designed specifically to test substation circuit-breaker Open and Close coils. The CBCT uses the substation’s DC power supply to electronically generate a programmable output voltage from 5% to 95% of the source voltage. The CBCT can maintain up to an 80A test current while maintaining 2% or better voltage regulation during the circuit breaker coil operation.
  • One continuous and one pulse DC output
  • Back-lit LCD screen (20 characters by 4 lines)
  • Output voltage programmable from 5% to 95% of the input voltage

CT-3500

Digital Circuit Breaker Analyzer

  
       
View Full Specs

The CT-3500 is a second generation, stand-alone, digital, microprocessor-controlled, circuit breaker timer. It measures elapsed time from the instant a breaker coil is powered to the instant of opening or closing of a circuit-breaker's dry contacts. The CT-3500 not only times the breaker's contact response time, but it can also time relays or other switching function that uses an initiating-trigger voltage (24-300 Volts dc or ac).
  • More accurate than Mechanical-Cycle Counters
  • Far exceeds the power utility industry's requirement for accuracy
  • No Conversion Calculation Required; Timing Results Display in Milliseconds & Cycles
  • Timing Results from all three Timers are shown Simultaneously on a Backlit LCD
