    Motwane’s Digital Contact Resistance Meter, Model PCRM-100S is specially designed to measure extremely low resistances in micro ohms. The instrument is based on the Kelvin four wire connection method for the measurement of low resistance. The selectable current injection is 100A. PCRM 100S has a large LCD with a backlight and displays real-time test information like injected current with measured resistance value & voltage drop. This user friendly instrument comes with heavy duty cables with clamps for accurate measurement and can be easily transported in its transportation case. Advanced Windows based software is provided for data downloading, analysis, and report generation. Internal memory of 99 records is provided for onsite data storage along with an in-built thermal printer to print the test results on the field.

    PCRM 100S has a dual ground technique to test circuit breakers with both sides grounded, which makes it safer to conduct tests in substations

    PCRM 100S has a Bluetooth connectivity module with Motware mobile app for remote access of testing data & storage in the cloud for further analysis & record purposes.

     

    Application

    Stationary and moving contacts are built from alloys that are formulated to endure the stresses of electrical arcing. However, if contacts are not maintained on a regular basis, their electrical resistance due to repeated arcing builds up, resulting in a significant decrease in the contact’s ability to carry current and an increase in resistance. Excessive corrosion of contacts is detrimental to the breaker’s performance. Hence to check contacts, apply DC and measure the contact resistance or voltage drop across the closed contacts. The use of a higher current value gives more reliable results than using lower current values. The resistance value is usually measured in micro ohms (μΩ).

    PCRM-100S is specially used to measure static contact resistance of LV, HV, EHV circuit breaker contacts installed in energized switchyards. High accuracy and repeatability make it a reliable tool for quality assurance and easy operations. It is a very handy tool for quick maintenance checks in various industries. 

    Typical resistance measurement applications are: 

    Circuit breaker contact resistance 
    Bus bar joints 
    Isolator contacts 
    Weld joints 
    Bond resistance
