SYMAP® - Advanced Feeder Protection relay

SYMAP® F is designed for land and marine applications for protection, control, measurement and monitoring of low and medium voltages power systems. All protection functions in SYMAP® F can be activated simultaneously, and there are no limits to using all of them at the same time. Hence follows, that SYMAP ® F can be used in different switchgear and network applications.   SWICHGEAR Control and Interlocking • single busbar • double busbar • duplex systems; • interlocking at feeder level; • interlocking at station level

NETWORKS • isolated networks, • resonant-earthed networks and • solidly, and partially earthed networks

Event History

SYMAP® automatically collects and stores all activated events indicating their number, title, coming/going status, and time stamp. A maximum of 5.000 events can be stored. In case of overflow, data overwriting operates according to the first-in-first-out (FIFO) principle.

Detailed Protection Function History

SYMAP® F automatically collects and stores all activated events related to protection functions with a time stamp.

        • Event number
        • Event title
        • Time stamp
        • Pickup or trip value (with fault phase indication)
        • Setting value
        • Trip time
        • 3-line voltage and current pickup, synchronized with the trip event

A maximum of 1.000 protection function events can be stored. In case of overflow, the oldest data will be recorded over.

Data Recorder (Option)

        • Number of samples (6 - 72)
        • Recording period (5 - 60 sec)
        • Pre-trigger (0 - 100%)
        • Trigger event (stop for recorder)


Diagnostics and Monitoring

SYMAP® F has three microprocessors that supervise each other, providing a watchdog system. Important functions are laid out in a double redundancy combination, operating independently with the second processor. Connected separately, an optional unit for short circuit protection operates parallel to the SYMAP® F device and will do so even if the entire voltage fails.

SYMAP® F provides various diagnostic and monitoring functions as follows:

        •  All memories (ROMs, RAMs, EEPROMs)
        •  All analog reference voltages
        •  Automated test sequences
        •  Control power ON/OFF of SYMAP® F
        •  Binary input and output for control logic

The following supervising systems are offered by SYMAP® F:

        •  Self diagnostics of SYMAP® F
        •  The inputs of analog data (auxiliary circuit)
        •  The status and position of switching device and motor's on-off status
        •  Supervising supply of trip coil
        •  Gas pressure
        •  Temperature inside panel
        •  Each operating life of breaker (hours)
