Line distance protection

Rel650 is ready-made distance protection for a 110-220 kV transmission line. It is the best solution for  protection of single breaker connected power lines and cables.

The standard set comes with fully prepared protection functionality and pre-installed settings.

In the model 650, the number of settings is significantly reduced, since most of the parameters are already set.

SPECIFICATIONS:

• Distance protection speed: 1.5 cycle
• Power swing blocking: yes
• Out of step and pole slip detection: yes
• Phase preference logic: yes
• Number of zones: 6
• Tripping[ph]: 1/3
• Back-up protection: basic
• Control of entire bay: circuit breaker only
• Communication:  61850-8-1 including GOOSE messaging

The presented device is used for highly sensitive protection of both overhead and cable lines. The device has a function of detuning from the load mode, which helps to detect damage through a high resistance. This option will be very useful for highly loaded lines.

REL650 fully complies with the requirements of the IEC 61850 standard. All devices in the series are part of the Relion® family of protection and control products.
