Jonathan Woodworth, arresterworks

"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."
