MEGGER SDRM201 -Resistance Measurement Accessory For Egil

The MEGGER SDRM201-Resistance Measurement Accessory For Egil is a sophisticated static and dynamic resistance measurement accessory designed to enhance the capabilities of Megger’s EGIL, TM1700, and TM1800 circuit breaker analyzers. This accessory is essential for professionals looking to perform detailed resistance measurements on high-voltage circuit breakers and other low resistive devices, providing crucial insights into their operational integrity and performance.

To utilize the SDRM201 effectively, the EGIL analyzer must be equipped with the SDRM option, ensuring compatibility and extended functionality. Additionally, users need to operate the system using CABA Win software, version R03A or higher, which is designed to support the advanced features of the SDRM201.

The SDRM201 accessory is specifically intended for both static (SRM) and dynamic (DRM) resistance measurements. This dual functionality allows for comprehensive testing and analysis of circuit breakers by measuring the current and the voltage drop across the breaker’s contacts. By performing these measurements, the SDRM201 helps in accurately determining the resistance values as a function of time, which is crucial for assessing the wear and health of circuit breaker contacts.

The complete system includes the SDRM201 unit along with essential accessories such as current cables and the SDRM Cable. The SDRM Cable, in particular, is a small yet vital component featuring integrated cables that facilitate the connection between the SDRM201 unit and the testing instrument. This streamlined connectivity is designed to simplify the setup and ensure reliable communication between devices during testing operations.

Utilizing the SDRM201 in conjunction with Megger’s circuit breaker analyzers provides technicians and engineers with a powerful tool for routine maintenance and diagnostic assessments of circuit breakers. By enabling precise resistance measurements, the SDRM201 accessory helps in identifying potential issues such as contact degradation or abnormal resistance changes, which can preempt failures and extend the lifespan of electrical infrastructure.
