EL KONTROL was expanded its license by ABB with the right to provide service and set-up of Middle Voltage frequency regulators.

The new license rights were acquired on the bases of ABB training procedure passed by our Service-station engineers, and after provision of the necessary equipment by EL KONTROL.

Since the beginning of 2015 we provide our clients with installation, commissioning, set-up, service maintenance, and training of operational personnel on ABB MV inverters of the latest ACS2000 series.

Project concerns reconstruction of 110 kV relay protection of two outgoing feeders from GPP-2 and opposite main step-down substations on the territory of the oil-refinery.

Order includes further reconstruction of relay panels and control panels; design of new fiber optic connections to provide operation of the relay protections; substitution of oil-insulated measuring transformers at 110 kV outgoing feeders and coupler breaker with new SF6 measuring transformers.

Contract for Design, supply of equipment for 6 kV Substation, dismantle of existing equipment, installation, tests and commissioning at OTF Rosenets includes elaboration of detailed design for substitution of 6 kV Switchgear with a new one equipped with vacuum circuit breakers, current transformers, microprocessor protection, and dry voltage transformers. Design also includes Secondary commutation part: control, signalization, protection, metering, automatic load transfer (ALT).

Company is awarded to install Substation Automation System (SAS) for 220/110 kV Switchyard of Varna TPP inclusive of producing protection and control panels, and supply of electrical materials for reconstruction of existing panels. Construction site is located in Ezerovo Village, Varna Region, Bulgaria.

Dipl. Eng. Stefan Yankov from ABB presented the innovative technological advantages of Emax2 air-insulated Circuit breakers.

ABB solution here is related to direct connection of the breakers to automation systems and energy management systems, as well as improvement of the productivity and the energy efficiency. Thanks to its novelty, aesthetics, high quality, applicability, functionality and productive efficiency this solution has showed to be excellent and won the Red Dot 2014 Design Award. Dipl. Eng. Yankov also presented ArTu type-tested panels giving examples for their certain application in various industrial enterprises.
