Contact resistance micro-ohm meter model RE-CR-100 is capable to measure resistance between 0.1 micro ohm to 20 milli ohm.

INTRODUCTION

Contact resistance micro-ohm meter model RE-CR-100 is capable to measure resistance between 0.1 micro ohm to 20 milli ohm. The instrument can provide test current between 0-100/200.....600 Amp subject to the load resistance and supply voltage. The system uses four terminal - two for current supply and two for measurement.

The Unit has high current capability and is of compact design suitable for testing high current contacts of circuit breakers, switches, bus-bar joints and other application where high current junctions exist. The unit is housed in M.S sheet housing, light in weight and supplied with 2 nos. current leads with clamps and 2 nos. potential leads with clips.

SPECIAL FEATURES  
    

•       Compact size for portability. 
•       Easy to operate and operation manual is provided.  
•       Built in safety arrangement for operator and equipment. 
•       Efficient after sales service   
•       Guaranteed for one year against manufacturing defects only.

Wherever voltage control is required, ‘RE’ Variacs makes it very simple by providing Toroidally wound Auto Transformer for variable voltage.

The ‘RE’ High Current Resistance Meter delivers high performance where it counts. With unmatched speed, range and accuracy it is the best solution for low resistance measurements on transformers, motors, breakers, switchgear, etc. Virtually all sizes of transformer can be measured – from small pole top units to the largest transmission units with Y or D configuration.
Extensive firmware provides fully automatic operation and a vast array of additional support functions. This new design responds to the needs of utilities and transformer manufacturers for a lightweight, portable unit with high accuracy and ease of operation. Its powerful 1 kW/2.5 kW DC power supply and the processor controlled circuitry are more than adequate to handle even the most demanding measuring application

SPECIAL FEATURES
   

•       Capable of winding resistance measurement of virtually any size and type of  transformer, single or three phase, delta (Ω) or star (Y) configuration.   
•       Rapid discharge circuit greatly improves measurement procedure.   
•       High precision – typical 0.5%.   
•       Compact and rugged for field or factory use.   
•       Fully automatic operation.   
•       Three measurement channels plus RTD channel.   
•       Memory for storage of 99 measurement results and 2 measurement setups.   
•       Data transfer possible without additional software.
