COMPUTERIZED AUTOMATIC RELAY TEST SYSTEM
CVRT-S16
-
CVRT-S8 & S16 are ideal for automatic testing of ELECTRO MECHANICAL AND READ RELAYS (only DC relays) both for static and dynamic characteristics. This system scans at one stroke, all the parameters of the relay as per definition of test procedure. The test sequence can be pre-programmed and stored in the disk. You can select the tests as per your requirement. Can include or exclude the test and you can have several options to match your test definitions. Semi skilled person can be engaged for actual testing, as he need not make any settings and need not interpret the readings. The system conducts the tests and gives PASS / FAIL indication on overall test results. If a printer is connected, each test result will be printed.Test Parameters : -> Coil Resistance.-> PickUp/Pull In /Operating Voltage or Current Linear Ramp Method or Step Method.-> Measure Pickup Contact Gap FBB-LBB V or mA-> DropAway/Drop Out/Release Voltage or Current Linear Ramp Method or Step Method.-> DropAway Contact Gap FFB-LFB V or mA-> % Release Dropaway/Pickup-> Contact Resistance of all contacts both Front and Back contacts.-> Operating Time @ Set Voltage or Current.-> Contact Bounce or Chattering Time while Operating @ above-> Release Time @ Set Voltage or Current.-> Contact Bounce or Chattering Time while release @ above-> Difference of Operate Time - Release Time.-> Bridging Test or Non Overlap Test.-> Transfer or Traverse Times while Operate and release.-> Operate Time @2nd Set Voltage or Current.-> Release Time @2nd Set Voltage or Current.-> Power Consumption @ Rated Voltage.-> Coil Current @ Rated Voltage at Room Temperature.-> Coil Resistance Corrected to 20deg C.-> Timing Waveform Graph for all active Contacts.

Micro-Ohmmeters
RMO-G Series
-
The RMO-G is a portable micro-ohmmeter designed for contact resistance measurement of non-inductive test objects and applications with increased safety requirement. It tests medium and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links. Due to its Both Sides Grounded and Remote Control functionalities, the instrument accurately measures even in the most demanding environments, providing additional safety to testing personnel.The RMO800G is the most powerful portable micro-ohmmeter on the market with 800 A output current. RMO200G is our best seller in the USA. A user can choose the appropriate model depending on the output current requirement, from 100 A (RMO100G) to 800 A (RMO800G).We use an unbreakable plastic case with IP67 protective rating (with closed lid) for instruments’ housing. Although very portable and lightweight, RMO-G micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents. Consequently, it enables the usage of thinner/longer test cables. RMO-G generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. During the testing, it increases current before measuring and decreases current after the measurement. This significantly decreases magnetic transients and ensures great accuracy.Special current clamps measure a current through groundings when the instrument tests in Both Sides Grounded conditions. The instrument itself powers these clamps. If even higher safety level is required, the Remote Control feature enables the operator to perform measurements from distant locations.RMO-G instruments can store up to 500 measurements in internal memory. Also, they have a built-in thermal printer and USB flash drive available as an option. An additional option is the built-in High Precision module suitable for measurement of very low resistance, in the range from 1 to 30 µΩ, with 0,01 µΩ resolution.Our free DV Win software communicates with the RMO-G micro-ohmmeters via USB or RS232 interface. It allows a user to run the test remotely from a PC. Also, a user can download test results, analyze and generate fully configurable test reports through the software.
