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.

Circuit Breaker Analyzers & Timers
CAT Handheld Series
-
When it’s not practical to use conventional robust circuit breaker analyzers, a handheld circuit breaker analyzer and timer may come handy. DV Power has developed a unique CAT Handheld series. It is specially designed for testing of circuit breakers with one break per phase. Their compact and ergonomic design can provide a wide range of features and reliable operations in low, medium and high-voltage substations or in industrial environments.CAT Handheld series consists of two models, CAT-P and CAT-H. Both of them have a large (5,7 in) colored touch screen display. Because of that, test results are visible in dark places as well as in bright sunlight.Powerful internal Li-Ion battery of the instruments can last up to 8 hours of testing without recharging.CAT Handheld series records:main contacts operating times,contact synchronization,sequence time,a resistance of pre-insertion resistors,open and close coil currents,main contacts bounce time,auxiliary contact time,DC Voltage.Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by triggering signal from current clamps connected to circuit breaker coil.CAT-H is capable of performing a coil control, while this feature is optional at CAT-P instrument. In contrast to CAT-H, CAT-P instrument can execute “First Trip” test.Both instruments display numerical and graphical results. Because of that, a user can easily overlay up to 4 records in the graphical form and make a quick on-site analysis of potential defects.A user can download test results to a PC via Bluetooth interface for more detailed analysis using DV Win software.

Counters and Timers
-
Orbit Controls counters and timers are designed for connection to practically all industrial sensors and pulse sources . They can be used as process monitors to display the process variable to be measured or as process controllers for control and monitoring tasks. The devices display and process pulses and frequencies, as well as quadrature signals from incremental and absolute encoded rotary encoders. In addition to information on the display, the devices also generate data and analog outputs and monitor preselected limit values. The process parameters are entered via the keyboard so that the display is calibrated in the required units and the output signals, serial interfaces and limit values are optimized.

Circuit Breaker Analyzers & Timers
CAT Standard Series
-
Circuit breakers are being tested during manufacturing, commissioning or maintenance stages. The most basic test requires timing measurement using circuit breaker timer. Their primary role is timing and motion measurement of medium and high voltage circuit breakers. Devices from CAT Standard series have suitable application in:electric power generation,distribution system,part of the electric power transmission system,contractors testing,and industrial environments.CAT Standard series meets the requirements of an easy to use circuit breaker timer and analyzer with an attractive price. Furthermore, they are portable and lightweight (weighs only up to 7 kg). Finally, the plastic case is unbreakable and has IP67 protective rating when the lid is closed.CAT Standard series includes five models:Three circuit breaker timers – CAT03, CAT31, and CAT61Two circuit breaker analyzers – CAT34 and CAT64CAT03 is a basic model intended only for timing measurement of main contact operations on the circuit breaker with one break per phase. Unlike CAT03, CAT31 has the possibility of circuit breaker operation initiation, coil current measurement, and auxiliary contact timing measurement. CAT61 differs in comparison to CAT31 by its ability to measure up to two breaks per phase.CAT34 and CAT64 are more advanced compared to CAT31 and CAT61, respectively, since they have additional analog channels. Also, they have the possibility of a travel curve recording.A user can download the test results to a USB memory stick or save it to internal memory. The CAT Standard series internal memory can store up to 500 test results (numerical and graphical data). Optional thermal printer prints test results in tabular and graphical form on 80 mm (3.15 inch) paper rolls. CAT Standard series instruments are compatible with DV-Win software. It provides full control of all CAT functions from a PC, as well as acquisition and analysis of test results.

Counters, Timers, And Ratemeters
-
ORTEC offers the broadest range of nuclear counters, timers, rate meters and multichannel scalers. Counters simply count the number of input pulses received during the counting period. Timers count pulses generated by an internal or external clock and are used to measure elapsed time, or to establish the length of the counting period. Rate meters provide a readout of the pulse count rate. Multichannel scalers count the number of events that occur during a specified time interval, referred to as the dwell time, resulting in a time-histogram of counts. “Standalone” and programmable computer controlled versions are available.

General Purpose Radiation Survey Meter/Geiger Counter
Rad 100™
-
The RAD 100™ is a general purpose radiation survey meter/geiger counter that detects and measures alpha, beta, gamma, and X-radiation. It is intended for personal safety and educational purposes. Like the popular Radalert® 100X, the RAD 100™ features a 3-second update on its digital liquid crystal display (LCD). The LCD shows the current radiation level in your choice of microSieverts per hour (SI units) or mR/hr for gamma radiation measurements. For mixed sources (alpha, beta, gamma) the CPM mode is recommended. This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours. A red LED blinks and a beeper chirps with each count (the chirp can be muted). This is a professional instrument that is also easy to learn to use and to operate, and carries the industry leading Medcom warranty (2 years overall limited to 1 year on the GM sensor). Many instruments designed by the Medcom team are still working perfectly after 30 years of use, so this instrument should provide a lifetime of useful information.
