Contact Resistance Measurement System
CRMS
-
The CRMS is a system designed to allow any user to measure the resistance of each set of relay contacts associated with the relay under test. The test system consists of a CONTACT RESISTANCE MEASUREMENT UNIT (CRMU), a MULTIPLE RELAY TEST RACK, as well as an interconnect CABLE ASSEMBLY. Either DC or AC energy to pick and drop relay coils under test for all contact measurements is supplied from the CRMU and easily interfaces with the Multiple Relay Test Rack. For additional and more thorough testing of relays an external relay tester can be interfaced to the Multiple Relay Test Rack to supply energy to the relay coil. It is recommended that the UTE Relay Tester With Timer/Counter (UTE Product # 15967-00) be utilized so the operator can take full advantage of the unique features it offers

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.

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.

An add-on option for the CableEye HVX high voltage cable tester series that permits expanded testing for contact and wire resistance as low as 1 mΩ. After checking for opens, shorts, miswires, and resistance limits, the 4-wire Kelvin measurement applies a user-selectable test current from 10 mA to 1 A to determine connection resistance within 1 mΩ. The resistance profile of a model cable may be stored and used as a basis of comparison during later testing to reveal cold solder joints, faulty crimps, recessed pins, pin contact contamination, improper wire gauge, and stress-extruded wire.This option may be purchased with any new HVX tester, or added as an upgrade to any of your existing HVX testers.
