What Our Clients Say

Powerlink Queensland successfully investigated the role that externally gapped line arresters (EGLA) could play in the future development roadmap for key transmission corridors on its network. However, given there was much to catch-up on for this technology, Powerlink engaged Metarresters to assist in several key areas including RCM analysis of EGLA’s, and development of a purchasing specification. This needed to cover technical and type approval requirements that were practical and reflected best manufacturing practice across the existing group of potential suppliers to Powerlink in this area.
Metarresters provided key support in this area, especially given the ongoing evolution of international technical standards for this technology.

Trusted by Industry Experts

"I have been involved in the surge arrester and surge protection industry for over 40 years. During that time, I have worked in all aspects of arresters as a consultant on the protection of power system. Also, during this time, I have  been an  active member of both IEEE and IEC standards.  These activities have presented me the opportunity to work and associate with Florent on numerous  occasions.  Over the years I have encounter and worked with most of the world experts in this field.  I can say with certainty that Florent has become one of them.  Should you need a hardworking, enthusiastic, and trustworthy person to assist you in surge protection, you should not hesitate to call on Florent."
