   Our Services


We conduct exhaustive Preventive Maintenance Inspection on various equipment used in power generation, transmission and distribution using sophisticated and specialiased instruments. Our teams of well-trained engineers carry out tests and conclude the results in the form of excellent reports that lead to actions to be taken be the power utilities to increase the life of such equipment by timely maintenance and avoid breakdowns. This results in huge direct and indirect savings in terms of equipment replacement and power outage cost.
