Client satisfaction is our core value


I would like to thank Merytronic for their participation during the underground cable routing from one of our Transformer Substations in Asturias, and highlight the good performance of the MRT-700 mapper. I would like to mention how intuitive the virtual cable representation on screen is, as well as the on-screen indications that help to discriminate other cables with returns or coupling, making the underground cable routing simple, fast and reliable.


In order to ensure the highest levels of availability of electrical energy to our customers, it is important we can rely on correct connectivity information. To check the reliability of this information, ENEXIS uses the ILF-12 connectivity instruments produced by Merytronic. In our distribution network. The ILF-12 has proven to be a very reliable tool, and is easy to use. Even users, who had no special training, can operate the instrument correctly. We can recommend the ILF-12 to other utilities.

EDP – HC Distribución

Merytronic is a regular and sole supplier of LV connectivity portable indentifiers (ILF12) in the last 4 years, and their solution permits us to get the mapping of the LV network.


Merytronic is a regular supplier of IBERDROLA of Advanced Low Voltage Supervision systems for LV network supervision. During this and last year MERYTRONIC has been awarded with relevant quantities of our LV monitoring deployment. In addition, ARIADNA INSTRUMENTS, technology partner of MERYTRONIC, is a regular and sole supplier of LV connectivity portable identifiers, and their new system to identify feeder mapping using smart meters and Advanced LV Supervision meters has been selected as the standard technology to be deployed in our network.
