Crest Test Systems Pvt. Ltd.
Measuring contact timings is useful for finding the contact bounces and non-simultaneity of contacts. This helps in finding the possible electrical or mechanical defects in the circuit breaker contacts. Timing analysis also make it possible to detect incorrect mechanical adjustments and wear phenomena of the circuit breaker by measuring the differences between the fastest and slowest phases.

CAT-H Series -
Amperis sl
The operation of the breaker can be initiated in different ways (e.g. from a control room, by a local breaker or externally by a test device) depending on the test conditions. Various time measurement triggers are available to record a measurement under a different test condition:*Coil control channel*Continuous current clamping channel*DC voltage channel

PI-5000 -
ETI Precision
The PI-5000 is composed of the PI2500 and the AUX-5000 auxiliary output unit, which when combined gives the unit the capability of testing 4000 ampere breakers, with essentially the same specifications as the proven PI-4000B. The auxiliary unit is smaller than the PI2500, so it can also be maneuvered easily in tight spaces, or lowered into shafts and manholes that would not be possible with a larger single piece unit.

Vanguard Instruments Company, Inc.
The Vanguard Auto-Ohm 10 is a 10-ampere battery powered micro-ohmmeter designed for low-resistance-measuring applications such as the measurement of resistance in circuit breaker contacts, bushing contact joints, and welding joints. The unit is powered by four 3400mAh, 3.7Vdc Li-Ion rechargeable batteries. With these high capacity batteries, up to 2,900 tests per charge (10A/2 second duration) can be performed in the field.

ACTAS C160 -
KoCoS Messtechnik AG
Stationary test system for carrying out fully automatic final factory tests, type and function tests on all kinds of switchgear devices, such as circuit breakers, disconnectors or earthing switches, regardless of the type of drive unit. All the electrical and mechanical parameters needed for the assessment of switching performance are measured in real time and evaluated without either the main contact chambers or the drive unit having to be opened. The system has analog and incremental input channels for the acquisition of analog quantities.

PI-800 -
ETI Precision
The PI-800 Circuit Breaker Test System incorporates modular design and flexibility to provide unequaled capability in a portable package. The PI-800 generates continuous current of 800 amps at 4.2 kVA, with peak output to over 10x, on 120 or 240 VAC supplies. The units are housed in rugged interlocking suitcase sized enclosures. Each piece weighs no more than 125 pounds, allowing one person hand truck mobility. Basic operation is very simple, and the proven MAC-21 instrumentation provides optimal output control and measurement.

MAC-21 -
ETI Precision
The MAC-21 uses proven microprocessor and A/D converter technology to provide real-time waveform analysis. This ensures accurate true-RMS readings of current pulses, even with DC offset and distortion, which are typical in primary injection testing. Intelligent threshold algorithms provide accurate trip time measurement. Integration of measurement and control functions allow advanced features such as preset on times, auto ranging, and optional printer or computer interface.
