Description
The Megger SDRM201 CG-90250 is a static and dynamic resistance measurement accessory for the EGIL. The EGIL must be equipped with the SDRM option, and you'll need CABA Win version R03A or higher.
The SDRM201 is intended for static and dynamic resistance measurements (SRM and DRM) on high-voltage circuit breakers or other low-resistive devices. Using the SDRM201 with the test instrument, you can measure the current and voltage drop across the circuit breaker contacts. The measuring unit can then calculate the resistance as a function of time.
The system consists of an SDRM201 unit with current cables and an SDRM Cable. The SDRM Cable is a small box with integrated cables for connecting the SDRM201 and the test instrument.
Key Features
