The Vanguard DIGITMR S2 is an inexpensive, easy to use digital circuit breaker analyzer. The DIGITMR S2 can be operated stand-alone or can be computer-controlled. It can fully analyze a circuit-breaker’s performance by testing the contact time, stroke, velocity, over-travel, and contact wipe. Contact and motion analysis can be performed for all breaker contact operations (Open, Close, Open – Close, Close – Open, and Open – Close – Open). Timing results are recorded and displayed on the 240 x 128 pixels back-lit LCD screen and can also be printed on the built-in 4.5″ wide thermal printer.

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.

Earth Tester
TAURUS PRECIOHM ET
-
The TAURUS PRECIOHM ET is one of the specially designed products by TAURUS to measure earth resistivity and earth resistance in a power station. These tests are performed based on 4 point (Wenner) and 3 point (fall of potential) methods respectively. All electrical equipment in the substation and power stations are electrically connected to station earth mat with earth electrodes. The earth electrode ensures that in the event over voltage on the system due to system fault or lighting discharges etc., the parts of the equipment which are normally ”dead” as far as voltages are concerned; do not attain dangerously high potentials. An earth electrode will only be effective so long it has a low resistance to the earth and can carry large currents without deteriorating. Thus the resistance of earth electrode should be low to give good protection and it must be continuously measured and monitored in all the substations and power stations.

PeakTech Prüf- und Messtechnik GmbH
A Rugged sealed digital earth tester is built with all the protection you need for outdoor use. The instrument is suitable for the testing of single earth electrodes such as lightning conductors and other small earthing systems according to VDE 0413. The resistance of conductors such as continuity and conduit coupling joints can also be measured. Two-terminal operation measurement, which reduces the accuracy, can also be done by shorting P and C terminals. It has an advanced circuit design that permits the instrument to operate with the minimum influence from earth voltage and earth resistance of the auxiliary spikes.

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.
