Dynamic resistance Measurement Kit - ZDRM-2

The Dynamic Resistance Measurement KIT ZDRM-2 implements a new method developed by Hydro-Québec research center (IREQ) and commercialized under licensed by Zensol.

See in the Photos section, Fig. 1: Results obtained with Old Method and Fig. 2: Results obtained with New Method.

The KIT has been designed to determine the main- and arcing-contact resistance curve (Fig. 1). The Zensol KIT allows to use a new method to obtain a "clean" resistance curve (Fig. 2), thus providing a reliable diagnostic tool for assessing the status of the breaker contacts.

• Easy and straightforward interpretation of the resistance curve
• Easy detection of faulty contacts (excessive wear, misalignment, etc.)
• Accurate values of the main- and arcing contact resistance
• Accurate values of the main- and arcing contact wipes
• Simple mathematical algorithm for assessing the status of the breaker contacts
• New test method validated on high-voltage air-blast and SF6 gas circuit breakers
• Instantaneous display of the results via the CBA Win© software
• Direct connection to the CBA-32P© circuit breaker analyzers
