    Motwane’s PCRM-100SM is a true DC Contact Resistance meter designed to provide accurate and reliable results at a very reasonable cost. The instrument is based on the Kelvin four wire connection method for the measurement of low resistance. PCRM 100SM has a true 100A DC test current suitable for testing Circuit Breakers, Bus Bars, Isolators, Cables, etc. PCRM 100SM has a dual ground feature considering the safety of the operator and equipment. PCRM100SM is very lightweight and easily portable, and comes with heavy duty test leads with C clamp and crocodile clips to suit different applications.

    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 builds up due to repeated arcing, 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-100SM 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
