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.

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.

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).

ELM Electronic Load Module
-
Circuit breakers are often overlooked during maintenance of electrical systems in aircraft, or often only verified for open and closed states. To test the true functional purpose of a circuit breaker it requires the application of current in excess of the rated trip value and then measure the time for the breaker to actually trip. This is the only way to verify that a circuit breaker will react as designed if an electrical failure occurs.

Circuit Breaker Analyzers & Timers
CAT Advanced Series
-
DV Power circuit breaker analyzer and timer utilizes the latest technological enhancements for safe and fast testing of circuit breakers. The sophisticated design ensures efficient and reliable operations in high-voltage substations and industrial environments.The CAT Advanced series are stand-alone or PC-controlled digital instruments for a circuit breaker testing. The timing channels record closing and an opening of the arcing, resistor, and auxiliary contacts. Also, the main contact channels can measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).With CAT Advanced series instruments, it is possible to record graphs of open and close coil currents. Furthermore, it records displacements of the HV and MV circuit breaker moving parts. Test results can be saved via USB, PC or be printed via 112 mm (4.4 inches) thermal printer (optional accessory) in tabular and graphical form.A circuit breaker test consists of different operational modes and CAT Advanced series supports:Open (O)Close (C)Reclose (O-0,3s-C)Trip free (CO)O-0,3s-COOpen-Close (O-C)Close-Open (C-O)Open-Close-Open (O-C-O)First trip (O)Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by sensing a breaker’s contact position.The auxiliary inputs are used to monitor dry and wet auxiliary contacts. The six coil control analog channels measure and record coil currents simultaneously (OPEN and CLOSE), up to 35 A AC/DC.The additional six voltage analog channels have four selectable voltage ranges available (±1 V, ±5 V, ±60 V and ±300 V AC/DC).A built-in micro-ohmmeter generates up to 500A true DC ripple-free current with an automatically regulated test ramp that provides performing static and dynamic contact resistance measurement.Three transducer channels provide a measuring displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time and average velocity. Also, a user can connect either an analog or a digital transducer to these universal channels.
