Shri Mangu Singh, Managing Director/DMRC has asked DMRC officials to conduct an audit into the different types of electrical related failures on Line-3 so that the pattern of the failures could be studied and analyzed with the intention of finding technical methods to minimize the occurrence of such incidents as far as possible. The audit will be conducted by a technical expert of the electrical department of DMRC who will go into the various technical aspects associated with each electrical failure of this line.
