Protection for distribution feeders and transformers
For MV/LV distribution networks SYMAP® solutions cover protection and control of feeder cells, transformer cells, connection cells, cable and line connections, and integration with SCADA/DMS systems. Typical functions include overcurrent, earth-fault, directional, voltage/frequency, distance and line-differential protection, together with measurement circuit, trip circuit, breaker, communication and event supervision in the network.
SYMAP® Compact+ is considered as a compact Protection & Control IED for individual MV/LV cells, particularly when protection, breaker control, metering, signalling, interlocking, communication and local logic are required in a single device. The classic SYMAP® series is considered for more complex distribution and system applications, standardization of a larger number of cells, retrofit projects, existing SYMAP® / HIMAP architectures, or when dedicated application variants are required for feeder, transformer, distance or line-differential protection.
