Monitoring the technical condition of power transmission lines (PTL) is vital for the stable and uninterrupted transmission of electrical energy. Our company offers modern solutions for the comprehensive inspection of PTLs, ensuring the reliability and safety of your energy infrastructure. One of the main directions within this service is the precise determination of the location of potential or existing damages on the lines. By quickly identifying the location of faults that may arise due to adverse weather conditions, mechanical impacts, or aging, we facilitate the acceleration of repair work and minimize interruptions in energy supply.

Furthermore, we also provide periodic checking of the insulation resistance of the lines. The condition of insulators can deteriorate over time due to environmental factors (pollution, moisture) and operating conditions. Regular measurement of insulation resistance allows for the early detection of potential short-circuit risks and insulation breakdowns. As a result of these checks, the lifespan of the equipment is extended, the overall safety of the system is increased, and energy losses are prevented. With our professional team and modern equipment, we are ready to ensure the continuous and efficient operation of PTLs.

Transformers are essential elements of power transmission and distribution systems, regulating voltage levels. Regular technical diagnostics are crucial to ensure their reliable and long-term operation. Our company performs the following main checks as part of comprehensive transformer inspections:

Firstly, by determining the transformation ratio, we verify that the transformer accurately converts voltage to the required level. This parameter is essential for the system to operate in normal mode and for the correct setting of relay protection.

Secondly, through periodic inspection of winding resistance, we assess the integrity of the windings, the quality of internal connections, and the condition of the voltage regulator contacts (if present). This test helps identify potential sources of overheating and defects that could cause energy losses in a timely manner.

Thirdly, we determine the condition of the insulation, the most sensitive part of the transformer. Through insulation resistance and other specific tests, we ascertain its degree of moisture, contamination, and aging, thereby preventing internal short circuits and the potentially severe accidents that could result. These checks increase the reliability and service life of your transformers.

Relay protection and automation (RPA) systems are complex devices designed to protect equipment from damage during short circuits, overloads, and other abnormal operating modes in power systems, and to ensure the stability of the network. Keeping these systems in constant working order is critically important for the reliability and safety of the power supply.

One of the main services we offer in this area is the periodic inspection of maximum current protection (MCP). Maximum current protection is one of the most fundamental types of protection that activates when it detects that the current flowing through the protected element exceeds a predetermined value, disconnecting the damaged part from the general network. During the inspection, parameters such as the pickup current and time delay of the MCP relays are checked, and the operational integrity of the relay itself and the breaker (circuit breaker) it activates is ensured. These periodic checks guarantee that the protection will operate correctly and reliably when truly needed, thus preventing costly equipment failures and long-term interruptions in the power supply.
