Our products regularly undergo attestation tests and have certificates of suitability for use in the power system issued by authorized institutions. Following the latest global trends in information technology, we have established cooperation with international attestation laboratories in order to confirm that our solutions meet strict requirements set by international standards.
Using entrepreneurship support programs and our own resources, we constantly modernize and expand our machinery park and laboratories. Modern surface assembly line of electronic components, CNC machine tools or microprocessor protection testers are some of solutions facilitating production and development of our Company.
Busbar and breaker failure protection systems for HV grid power substations are our flagship products, fully designed and produced in-house. Protections type TSL/TL/TS of various generations work in hundreds of national switching substations (400, 220 and 110 kV). These systems are individually designed for the specific busbar arrangement and can be made for simple “H-arrangements”, for multi-system busbar with transfer buses as well as busbar unconventionally arranged.
We have extensive experience in the design and manufacture of emergency signalling systems for power substations. Our signalling systems MSA-type are used for newly built and modernised substations as well as for older stations where old, exploited devices are changed for modern ones. Substations having our signalling system gain a clear disturbance visualization system enabling transmission of signals to the control system over digital channels as well as recording of these signals.
We offer development, production, assembly and commissioning of auxiliary power supply switchgears for the substation’s own needs. We suggest to equip AC switchgears with automatic stand-by switching-on system SZR-type of our make and the DC auxiliary power supply with an earth-fault monitoring system KDZ-type also of our make. In recent years, we have focused on expanding the list of offered devices, successfully introducing to the market an RZS-type disturbance recorder, which is now operating on many objects of the national power system. Our latest achievement is the development and positive certification of a series of bay protections for the 400/220/110 kV network TZX- type. The series includes ground fault protection, transformer differential protection, distance protection of the line, and further also a longitudinal differential protection of the line. Our protections and other devices have the ability to communicate with control systems through different physical layers of serial connections and communication protocols. We implement communication in ZP-6 (proprietary) protocol, IEC 870-5-103 protocol, as well as in accordance with the latest IEC-61850 edition 1 and 2.
