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

Transformer Winding Resistance Meters
RMO TT Series
-
The Tap Changer Analyzer & Winding Ohmmeter of the RMO-TT series is designed for winding resistance measurement of inductive objects, and for a tap changer analysis. The RMO-TT series is based on the state of the art technology, using the most advanced switch mode technology available today. The RMO-TT instruments are accurate (0,1%), powerful (up to 100 A) and still portable. The Instruments generate a true DC ripple free current with automatically regulated measurement and discharging circuit. RMO-TT instruments can perform a simple, quick and reliable transformer on-load tap changer condition assessment. This series of instruments enable measurements of a winding resistance in every tap position, current ripple values (percentage of a current drop during a tap change) and transition times during the tap changes. Problems with a connection, contacts, and selector/diverter switch operation (tap change with interruption) can be detected with these measurements.
