ISO certified, proud and safe

Of course we are ISO certified. This means that you can be sure that the job that is performed satisfies all the requirements that are set.

We measure everything

Regardless of whether it is a matter of measuring earthing systems on line networks, for measuring in complex industrial plants and large power stations, we can measure and control it. All in accordance with updated regulations and norms.

Our expertise

Trainor's tasks include everything from measuring earthing systems on grids to measuring large, complex industrial facilities and power stations. We carry out measurements of transition resistance for earth electrodes, earth connections and resistivity, and prepare documentation pursuant to regulations and standards.

Our methods

We use modern, efficient measuring methods for checking earthing electrodes and ground connections, and provide all necessary equipment and highly qualified personnel to head the entire measuring task. All our engineers and assistants complete annual updating on FSE (high and low voltage) and first aid courses, and if you wish, your personnel may participate in measuring tasks to learn some of the basic principles of measuring techniques.
