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
  • Built-in, single channel timer

The CT-3500 S2 is Vanguard’s second generation, stand-alone, digital, microprocessor-controlled, circuit-breaker timer. It measures the elapsed time from the instant a breaker coil is energized to the instant of opening or closing of a circuit-breaker’s dry contacts. In addition to timing a breaker’s contact response time, the CT-3500 S2 can also time relays or other switching functions that use an initiating trigger voltage (24-300 Volts DC or AC). The timer-triggering voltage starts three independent electronic timers.

  • Detect Main & Insertion Resistor Contacts on same input
  • USB computer interface
  • USB Flash drive interface (Flash drive not included)
  • Store 128 test records internally
  • Initiate Breaker Operation
  • Built-in 2.5" wide Thermal Printer
  • Rugged "QWERTY" style membrane keypad

The CT-7000 S3 is Vanguard's fourth generation EHV circuit breaker analyzer. The CT-7000 S3 is available with 3 (part number 9021-UC) or 6 contact timing channels (part number 9100-UC). The CT-7000 S3 can fully analyze a circuit breaker's performance by measuring the main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes. Both contact and motion analysis can be performed on all circuit breaker operations (OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN, and OPEN CLOSE-OPEN).

  • Fully analyze circuit breaker's performance by measuring main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes
  • USB computer interface
  • USB Flash drive interface (Flash drive not included)
  • Store up to 200 test records and 100 test plans internally
  • Initiate Breaker Operation
  • Built-in 4.5" wide Thermal Printer
  • Rugged "QWERTY" style membrane keypad
  • Optional "On-line" Timing Mode
  • Optional dual ground testing mode
  • Optional Bluetooth wireless computer interface
