stucke GROUP SYMAP Digital Protection Relays

stucke GROUP  SYMAP Digital Protection Relays 

Assuring the availability of energy on land and at sea as well as safe energy supply solutions through network protection and control systems – this is what stuckeGROUP products and solutions offer. 

Made in Germany – we manufacture our products, including development, exclusively in Hamburg. Our multifunctional protection and control systems offer engine control as well as comprehensive protection functionalities for generators, motors, transformers and other feeder lines, besides distance line differential and grid protection. Functionalities include power management, DP system logics, arc protection, reactive power undervoltage protection, grid decoupling and power plant control for low, medium and high voltage systems, for gas and diesel engines, gensets and power units as well as hybrid systems. They stand out for reliability and longevity, and we hold spare parts for all product generations on stock. 

Our customers are for example system integrators, shipyards, shipowners and -managers, designers, owners and operators of power plants, sites for generation of renewables or of emergency energy systems. Customer focus, a profound understanding of customer needs and prompt availability are important for us. 

The project department offers our customers planning, design, production, installation and commissioning of complete and tailor-made switch and control cabinets for low and medium voltage solutions. 

Our company is certified according to DIN EN ISO 9001 and 14001.

SYMAP® 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 switchboards. With three powerful microprocessors SYMAP® offers comprehensive protection functions for generators, motors (synchronous and asynchronous), transformers, power lines and distributions. 

All protection functions can be activated simultaneously. With SYMAP® five main breaker controls can be activated with all necessary functions such as display, control and blocking for optimal breaker manage ment. A small integrated PLC allows individual functionality, such as 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.
