 Product
OverviewSYMAP® is a flexible microprocessor-based digital protection device for use in low, medium, and high-voltage power systems. Because of its integrated protection functions and human-machine interface capabilities, it is an efficient and cost-effective solution for all types of switchbays.With three powerful microprocessors, SYMAP® offers complete protection functions for generators, motors (synchronous and asynchronous), transformers, power lines, and distributions. All protection functions can be activated simultaneously, and there are no limits to using all of them at the same time.  With
SYMAP®, five main breaker controls can be activated with all the
necessary functions, such as display, control, and blocking, for optimal
breaker management. A small integrated PLC allows individual interlocks
from controlling functions. For flexibility in commissioning and during
use, both digital and analog outputs can be used to connect the SYMAP®
control unit to main switchboard controls. Additionally, a variety
of serial interfaces with different kinds of protocols can be used
for communication between SYMAP® units and the central control
system. For diagnostics and monitoring, SYMAP® 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® device and will do so even if the entire voltage fails. Human Machine Interface SYMAP® is easy to program and operate. A large graphic LCD with optional LED indicators conveys important data, such as position of all connected breakers, parameter settings, and event histories, at a glance. Graphics and measurements are displayed side-by-side on the LCD, so that the user does not have to switch between pages. The entire programming of SYMAP® can be done with the keys on its front panel, eliminating the use of external programming devices. The programming is built in and is menu-tree driven, making setting parameters an intuitive process - similar to inputting data in a modern handheld telephone. Optionally, parameters can also be programmed using a laptop computer. Using a laptop offers certain advantages, such as parameter data stored in the laptop can be easily input into other SYMAP® units. Either way, ease of programming is guaranteed and on-site visits by the manufacturer's engineers during commissioning are not required. 
SYMAP® provides four hotkeys under the LCD offering access to four groups of values:
Under the hotkey "Meters," detailed information of electric measurement values, counters for active and reactive power, and of working hours is provided. Under the hotkey "Alarms," all active alarms, event stores, and blockings are displayed. Under "Process," all process data, such as synchronization display, motor thermal indication, and breaker counters, are shown. Under "Breaker Control," up to five breakers can be accessed and controlled. When programming breaker controls, the user has access to various layout configurations available through a library of graphics maintained within SYMAP®. Programmed blockings remain active when manual control of the breaker is used. Each of the highlighted breakers in the LCD can be further controlled by the keys "O" and "I." For security, access to SYMAP®'s parameter and breaker control data is protected by a code system. The code system offers dual access: by a transponder card or by password input.  Terminal Connections All connections to SYMAP® are made with terminal plugs on the back of the device, allowing the device to be exchanged easily. The terminal blocks are divided into four groups.  Analog Input for Measurement SYMAP® provides inputs for analog sensors at the rear of the device. If terminal plugs for the CTs are disconnected, the circuits will be linked automatically so there is no disconnection in the CT circuit loops. A total of 17 analog inputs for current and voltage transformers are used for protection functions. The following list shows possible connections for current transformers (CT) and potential transformers (PT):
By use of combined sensors, SYMAP® can provide:
Communication SYMAP® can serve as the main bay controller for the power management system or substation system. The following list shows the station system items available through SYMAP®:
Communication Interfaces SYMAP® can serve as the main bay controller for the power management system or substation system. It provides communication ports available with the following interfaces:
Extended Board (Optional) An extended board can be connected to SYMAP®, providing additional in and output channels. The extended board is customized to individual client requirements and can be equipped to a maximum of the following in and output channels:
Recording Unit SYMAP®'s recording unit contains up to three separate parts: 1) event history, 2) detailed protection function history, 3) event data recorder (optional). All data recorded by the unit can be transferred and analyzed via a PC tool. Regardless of power supply, the data store is permanent.
Event History SYMAP® automatically collects and stores all activated events with their number, title, appearing and disappearing status, and a time stamp. A maximum of 5,000 events can be stored. In case of overflow, the oldest data will be recorded over. Detailed Protection Function History SYMAP® automatically collects and stores all activated events related to protection functions with a time stamp.
A maximum of 1,000 protection function events can be stored. In case of overflow, the oldest data will be recorded over. Data Recorder (Optional) The data recorder can log 16 analog inputs, 14 digital inputs, and 12 digital outputs. The recorder has the following settings:
 The
recording period depends on the number of samples. The recorder can
be set with the pre-trigger in such a way as record event data even
before the event happens. Stopping the recorder can be triggered either
by an event or by a preset time. For easier management and trouble-shooting,
event data can be transferred and analyzed via a laptop computer.
The transfer of data is made by a link through a plug on the front
panel of the SYMAP® device.Diagnostics
and MonitoringSYMAP® 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® device and will do so even if the entire voltage fails. SYMAP® provides various diagnostic and monitoring functions as follows:
The following supervising systems are offered by SYMAP® :
Digital Protection Device There are three types of SYMAP® units as follows:
