Analyzers and Timers
CAT Advanced Series
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:

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.

Portable Relay Tester
The protective devices such as relays, overload coils, circuit breakers must be checked regularly to ensure that, they are always ready to operate correctly. If a fault occurs in the equipment, which they are protecting, routine relay testing will quickly detect the faulty, incorrectly adjusted protection circuit and will possibly prevent serious damage to plant or injury to personnel. Apart from checking the protective circuits correctly, it is usually necessary to measure its operating time. The micro controller based time interval meter is used for this purpose in all AJIT brand relay tester.

188 FFF
Standard Electric Works Co., Ltd
● The 188FFF doesn't have the function of the sensitivity adjustment. If the customers need the sensitivity adjustment function, plase refer to other models.● The 188FFF is a Fuse and Fault Finder which comprises of two parts : The Receiver and the Transmitter.● The Transmitter, draws a current from the mains supply circuit to which it is connected to. The Signal● Current from the Tx is at about 10kHz. The Transmitter is powered by the mains and requires no batteries.● The 10kHz signal current generated by the Transmitter is then searched(sniffed) by the Receiver to detect the Fuse, Circuit Breaker or the faulty circuit.● The Receiver is a tuned circuit which has it's center frequency tuned to about 10kHz. The sensor is located in the tip of the Receiver.● The amplitude of the received signal is shown on a bar-graph type Leds.● The more Leds ON, the stronger the signal.

Primary Injection Test Systems
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.
