The cable / line differential protection relay MCDLV4 is designed to be used pairwise for protecting cables and lines up to 24 km. There can even be an in-zone transformer within the line to be protected. In addition, it comes with a very comprehensive protection package like phase, restricted earth fault, inrush detection, and monitoring functions including grid interconnection and control functionality up to 6 switchgears.
The intuitive operating concept with plausibility checks and extensive commissioning functions such as the built-in fault simulator allows a safe and time-optimized maintenance and commissioning. The parameter setting and evaluation software Smart view can be used consistently across the entire family of devices.

Smart view is even capable of monitoring the remote MCDLV4 via the protection communication interface between the two MCDLV4 devices. The MCDLV4 is available in 576 variants, that cover all combinations of properties that you might need or not need for your application. Each variant is uniquely specified by a typecode of form MCDLV4-2xxxxxx (i.e. 6 digits/letters following the ‘-2’). Check the Order Form (depicted below, or in the brochure DOK-FLY-MCDLV4-2E or in the user manual MCDLV4-3.6-EN-MAN) for a complete overview.
With the HighPROTEC Line Woodward offers an outstanding solution for the reliable protection of
distribution and generator applications. The innovative device handling and PC tool with plausibility check and internal fault simulator, combined with high flexible hardware, minimized commissioning, training costs and setting failures. The menu overview can be optimized by hiding not relevant functions.

Woodward MCDLV4-Family Protection relay : Line Differential Protection

Woodward offers line differential protection with fiber optic communication, because it is the best way to protect an overheadline or cable. Speed is important for differential protection because it is the most selective protection. Since communication between the devices occurs via fiber optic connections, data transmission is not only especially fast, but also extremely safe.

In addition to complete line protection, Woodward’s System Line relays offer measuring and control functions and integrated backup protection.

The following relays offer Line Differential Protection.
