The world is changing very fast and power systems evolve even faster. Just a century ago overwhelming share of energy was generated by thermal and hydro power plants. Just fifty years ago nuclear power stations dominated in the international energy construction process. For many years the generator has been the most expensive and major component in electrical power systems. Today, Relematika ensures reliable solution and products for safe and reliable operation for different sources of electrical energy.
A huge renewable energy market is very attractive today. Many solar and wind renewable sources are interconnected to distribution and transmission systems. This initiates some important questions regarding complete system stability. We provide modern IEDs and solutions for distributed generation as well.
Relematika provides several types of protection and control cabinets designed on the basis of either TOR 300 GTP 510 (for protection of medium and low power generators) or TOR 300 GTP 511 (universal generator protection) to meet your business and technical needs.
Cabinets equipped with powerful microprocessor-based TOR 300 GTP devices provide complex relay protection of synchronous generators, either combined with a step-up transformer or operating in parallel with other generators to the same busbars. Two identical protection cabinets are installed to increase reliability of the complete protection scheme. Each of them includes the full set of protection functionality with independent operational, measuring and output circuits. As you can see, the duplication principle is implemented as a rule. Our delivery includes also the setting recommendations for all including protection and control functions.

Main functions
Relematika also produces microprocessor-based control devices for precise automatic synchronization of generators and consequently their connection to parallel operation with power system. These devices can be additionally used for connection of synchronous compensators.
The main functionality of the device is synchronism check (RSYN (25):
Power plants have a lot of medium voltage switchgears for supply of motors, auxiliary step-down transformers and so on. Small and powerful asynchronous and synchronous motors, as well as two-speed powerful motors and any outgoing feeders can be reliably protected by Relematika IEDs. The TOR 200 platform ensures a full range of protection, automation and control devices with optimal functionality, furthermore it guarantees excellent interoperability with SCADA systems by different interfaces and protocols including the IEC 61850 standard.
