ENGINEERING DESIGN
A complete range of activities such as pre-design services, engineering design and land investigation services for construction (reconstruction and modernization) of the electric power facilities are being performed by the company. The facilities we work on are:
- High voltage power lines of 0.4 – 750 kV;
- Transformer substations (including digital) of 0.4 – 750 kV;
- Switchgear and switchyards of the substations;
- Engineering networks and systems, fire prevention alarm and video monitoring systems;
- Renewable energy facilities.
Indispensable types of performed work are:
- Smart grid automation of electrical networks;
- Electricity quality automated monitoring and control systems;
ENGINEERING INVESTIGATION
By means of the modern methods and techniques, the company provides the following facilities investigation of:
- Building structures;
- Overhead high-voltage electric power lines:
- Defining the technical condition of concrete steel and metal support towers and portals;
- Controlling the technical condition of the conductors and grounding wires, line fittings and isolators;
- Investigating the facility electromagnetic environment;
- Performing the vertical electromagnetic ground sounding;
- Measuring the electrical networks operating parameters and the electricity quality values;
- Measuring the induced voltage values;
- Drone investigating the power lines.
CIRCUITS AND SCHEMES
The company is developing the following electrical circuits and schemes:
The power evacuation schemes of the electrical stations (from the Nuclear power plants to the Windfarms and Photovoltaic stations);
The electricity supply of the customers;
The power districts and energy nodes prospective development.RESEARCH AND DEVELOPMENT
The company conducts the scientific research in the electric power industry. We develop and supervise the implementation of:
- Technical standards and legal acts;
- The instructions on how to work on the power lines under the induced voltage;
ELECTROTECHNICAL LABORATORY
The laboratory is accredited to conduct the electromagnetic investigation at the 35 – 750 kV electric power plants and the electrical substations including:
- The resistance of the grounding devices;
- The specific soil resistance;
- The impulse distortions voltage in the secondary circuits, performed by the electromagnetic irradiation during the commutations and short circuits;
- The impulse distortions voltage in the secondary circuits, performed by the potential increase in the grounding device during the short circuit;
- The voltage of the commercial frequency, influencing the cable isolation of the secondary commutation circuits, provided by the short circuits.
The lab also measures:
- Electric and magnetic fields voltage of the commercial frequency;
- The induced voltage levels at the power lines.
