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.

First Trip Testing of Circuit Breakers
-
Significance of Circuit Breaker "First Trip Time"A circuit breaker may not be called upon to operate and clear a fault for years, but when a fault occurs, it is expected to operate within it's published time-current characteristics. Unfortunately, frequently this does not happen... environmental contaminants, hardened grease, vibration and other factors can adversely affect the operating time of the circuit breaker.

Description The Advanced CAT Series Analyzers and Timers are stand-alone or PC-controlled digital instruments for circuit breaker status evaluation. Timing channels record arc closing and opening, resistance and auxiliary contacts. The main contact channels can also measure the resistance value of pre-insertion resistors (if present in the breaker). The advanced CAT series records graphs of the opening and closing coil currents and the movements of the moving parts of the high and medium voltage circuit breaker. Test results are printed on the 112 mm (4.4 inch) thermal printer (optional accessory) in tabular and graphical form. The advanced CAT series provides easy selection of different operating modes:

Transformer Rectifier Assemblies
-
Transformer rectifier assemblies are very useful in OEM applications when unregulated DC output is required. Input power can be single-phase or three phases. With single-phase input power, the output ripple is 50%. With three-phase input power, the output ripple is 5%. A 5% output ripple is a clear advantage. Hence, transformer rectifier assemblies with three-phase input power are more popular. Circuit breakers, fuses, voltmeters, and ammeters can be added per customer requirements. The assemblies can be an open frame or inside an indoor enclosure.

The Motwane Manufacturing Company
High contact resistance values are a definite cause of the failure or less than optimal performance in a wide variety of electrical devices. Contact resistance testing is therefore most critical to measure the resistance of electrical connections in switching devices, circuit breakers, isolators, busbars, relays, joints, connectors, cables, and cable joints. The device helps to find destructive or corroded contacts and hence protects substation devices from damage.
