The first Intelligent Control Operation Disconnect ICOD prototype was tested in 2006 by Hydro Quebec, the largest electric utility in Canada. The ICOD was tested on a 765kV disconnect. Testing was completed by Hydro Quebec technicians and a full report was submitted by Hydro Quebec. During the testing at Hydro Quebec this early version of ICOD provided an improved control of the operation of the d
isconnect. And with its variable speed control ICOD reduced the arc time. By reducing the arc time exposure to harmful harmonics is reduced thus increasing the life of the adjacent equipment. Testing on an installed disconnect confirmed the need for a motorized control cabinet that included ICOD, therefore development team was formed to build a completed monitoring solution for disconnect switches which would be housed in a motorized cabinet manufactured by EHT. In 2009 the company was proud to offer a commercial version of iCOD for high voltage networks worldwide. Recent history :
-In October 2009, the United States Patent Office issued a Notice of Allowance for EHT’s key patent.
-In November of 2010 Patrick Lalonge was nominated President.
-In March of 2011 EHT moved to a new location in Boucherville Quebec as more space was needed for production, R&D and sales.
-July 2011 William Morse was nominated Vice President Sales and Marketing.
-In October 2011 the United States Patent Office issued a Notice of Allowance for EHT’s second patent.
