Digital Circuit Breaker Analyzer
CT-3500 S2
-
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. Each timer is individually stopped by its respective dry-contact closing or opening. The CT-3500 can fully analyze the timing of all circuit breaker operations (Open, Close, Open – Close, and Close – Open). Timing results are displayed in milli-seconds and cycles on the unit’s back-lit LCD screen and can be printed on the built-in 2.5-inch wide thermal printer.

Primary Current Injection Sets
-
Protective devices such as relays, overload Coils, Circuit breakers and CTS etc. must be checked regularly to ensure that they are always ready to operate correctly, Routine current injection testing will quickly detect faulty or incorrectly adjusted protection circuits / devices & will be possible to prevent serious damage to the system. Primary injection kit is designed to operate on single phase 230/240 volts AC 50 HZ to develop smooth & continuous test current as for loading, calibrating, and testing of CTS, Bimetal Relays, Protection Relays etc. The test set gives high current output at low cost and with inherent safety. The primary current injection testing checks all parts of the protection system by injecting current down the cable / bus bars. The application of the primary current injection sets is to ascertain the current carrying capacity of any Conductor, insulator, connector or calibration of CTS / Bi-metallic relays etc.
