CBCT Breaker Coil Tester
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.
MCCB-250 Molded Case Circuit Breaker Tester
The Auto-Ohm-200 S3 is Vanguard’s fourth generation, microprocessor-based, true DC micro-ohmmeter. It is designed for testing EHV circuit-breaker contact resistances, bushing contact joints, welding joints, or for any low-resistance measuring application. This high current and very lightweight (16.8 lbs/ 7.6 Kg) micro-ohmmeter is designed to meet the IEEE C57.09-1999 (5.15) requirement for testing circuit breaker contact resistance.
UPS S2 Universal Power Supply
The Vanguard Universal Power Supply Series 2 (UPS-S2) is designed and produced to meet a utility company's substation needs for an independent AC/DC power source. Both the AC and DC Voltage sources are capable of supplying 10 amperes continuously.
The Vanguard Resistor Transducer Adapter (RTA) can be used to connect any resistor type transducer to the digital transducer channel of a Vanguard circuit breaker analyzer. The RTA also features a 3-pin SwitchCraft connector that can directly interface with ABB resistor transducers.
CB Analyzer Test BoxCircuit Breaker Analyzer Test Box
The Vanguard CB Analyzer Test Box is designed as a field training/demo tool for the CT-7000, CT-8000, and DigiTMR. It can be used to verify the CT-7000/CT-8000/DigiTMR's timing function. The CB Analyzer Test Box provides 3 independent dry-contact channels to simulate the 3 phases of a circuit breaker. A built-in 12Vdc power supply is used to open or close the contacts. An OPEN or CLOSE command can be sent by using the front panel switches or the OPEN and CLOSE terminals. The contact status is indicated by LED's on the front panel.
The Doble Transducer Adapter can be used to interface any Doble travel transducer to a Vanguard circuit breaker analyzer.
CT-3500 S2 EHV Circuit Breaker Analyzer
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.
DigiTMR S2 Circuit Breaker Analyzer Test Box
The Vanguard DIGITMR S2 is an inexpensive, easy to use digital circuit breaker analyzer. The DIGITMR S2 can be operated stand-alone or can be computer-controlled. It can fully analyze a circuit-breaker’s performance by testing the contact time, stroke, velocity, over-travel, and contact wipe. Contact and motion analysis can be performed for all breaker contact operations (Open, Close, Open – Close, Close – Open, and Open – Close – Open). Timing results are recorded and displayed on the 240 x 128 pixels back-lit LCD screen and can also be printed on the built-in 4.5" wide thermal printer.
CT-7000 S3 Digital Circuit Breaker Analyzer
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). The CT-7000 S3's timing window is selectable between 1 second, 10 seconds, and 20 seconds.
CT-8000 S3 Digital Circuit Breaker Analyzer
The CT-8000 S3 is Vanguard's fourth generation EHV circuit breaker analyzer. The CT-8000 S3 is available with 3 (part number 9103-UC) or 6 contact timing channels (part number 9104-UC). The CT-8000 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. Also, an outstanding feature of the CT-8000 S3 is the ability to perform dynamic resistance tests on circuit breaker contacts.
CB PWS Circuit Breaker DC Power Supply
The CB PWS is a standalone DC power supply designed for operating circuit breakers. This compact and lightweight DC power supply can power the circuit breaker control circuit (trip and close coils, and charging motor) in situations where the substation DC supply is not available. The CB PWS is powered by a wide AC voltage source (120 -240Vac) and available with factory preset 120Vdc or 240Vdc output.
UPS S3 Portable AC/DC Power Supply
The Vanguard UPS S3 is an AC/DC adjustable output power supply designed to operate substation circuit breakers. The UPS S3’s AC and DC voltage sources can supply up to 10 Amperes during the circuit breaker coil energization and circuit breaker charging motor operation. Powered by a single phase 90-120 Vac voltage source, the UPS S3 provides an isolated adjustable AC/DC voltage source. Output voltages are variable via the front panel control knob. The unit's variable AC output voltage source (10-140 Vac) is rated at 140 Vac @ 9A continuous.
