Aging distribution infrastructure poses increasing obstacles and cost for the power industry. Industry-wide "go till they blow" policies have left large portions of utilities' distribution infrastructure rapidly approaching or exceeding expected service lifetimes due to preventable issues with equipment. Ignoring problems with distribution equipment seldom - if ever - lead to sudden, catastrophic increases in failure rates, maintenance, and replacement costs. Instead, situations slowly worsen each year but often remain frustratingly difficult to diagnose properly or manage effectively and economically.
The greatest problem in many systems is not the oldest equipment, but the "middle-aged" equipment. It is a fact that pad mount equipment built in the 70's thru the 90's was perhaps better-built or stronger than the equipment built in a later era. Manufactures of equipment have cut back on internal metals due to the high cost of metals. Example, it is a well-known fact in the utility industry that a 50 KVA transformer built in the 80's handle overloads without interruption, however replacing them with modern 50 KVA transformers will not withstand constant overloads.
By managing current equipment issues not only prevents pre mature failures, the cost of prevention is a small fraction of replacement cost. Utility Restoration Services Inc. has an affordable answer from identifying to resolution of pad mount equipment issues
Utility Restoration Services Inc. provides inspections on pad mount utility equipment. The benefits of inspections provide onsite views of problems in the field with equipment. Inspections include:
- Identification of equipment in the field including serial numbers, KVA, oil capacities, manufacture date, any relative information requested from serial number plate.
- Condition of cabinet and oil tank to report any issues such as oil leaks, corrosion problems, unsafe conditions, missing decals.
- Ensure transformer is at or "above grade" to ensure soil or other debris is not resting against cabinet causing an acceleration of corrosion and heat buildup in oil tank.
- Survey internal condition under lid to report ant or animal nest that will cause soil on firewall of tank to corrode oil tank. Fire ants cause connection corrosion, chew on insulation, and unsafe working conditions for technicians in field.
- Check for proper ID numbers, warning labels, and other pertinent information requested by utility.
- Security. Ensure pentabolts are in place, locks secured, and all access to equipment is secured.
