Contact Resistance Meter
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.

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.

Voltage Detectors
JSC-88AW
The JSC-88AW is a very reliable way to know for sure whether or not there is voltage downstream from the switches or breakers during power-offs. It dramatically increases the safety of personnel assigned to maintenance work on electrical equipment powered by three-phase voltage. As long as voltage is present downstream of the breakers, one or more (LEDs) of the JSC-88AW will stay lit. A simple visual inspection tells you whether the electrical system is in “Zero Energy” mode. In addition, this new device has been improved to enable resistance to voltage spikes (transients).

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.
