Preventative Maintenance



Property damage resulting from electrical breakdowns and failures can be severe.  Electrical equipment failure is the leading causes of industrial fires.  Implementing a regular plan for preventative maintenance helps equipment last longer and run more productively.  When equipment stops running, so does your business.

There are loss prevention steps you can take to reduce the likelihood of loss.  Because the risk is real and sometimes unforeseeable, a preventative maintenance program can reduce risk of an unscheduled outage by as much as 66%, according to statistics from the Institute of Electrical and Electronics Engineers (HSB June 2014).  Only use qualified and competent maintenance personnel to properly, safely and effectively maintain electrical power equipment.

Tips for keeping electrical systems safe:

  • Keep electrical rooms free of excessive dust and dirt
  • Do not use electrical equipment rooms for storage
  • Focus your program on preventative measures to ensure you are not allowing for an electrical fire, by keeping electrical apparatus clean, cool, dry and making sure connections are tight.
  • Test electrical equipment including transformer, circuit breakers, relays, etc.
  • Clean AND test – Both are key to a good preventative maintenance program.
  • Our Team of electricians and test technicians are: Skilled; Qualified; Trained; Outfitted with the right test equipment.

New 12.47kV Switchgear


Industrial customer had experienced several substation failures due to the age of their equipment.  They could not afford for its industrial production lines to be halted during the work week for the replacement of the 12.47kV switchgear and electrical components.  The customer sought an electrical design-build firm who was able to design, procure and execute the installation to meet their fast track schedule.


IETC provided fast track electrical design-build and construction services for the replacement of the switchgear and distribution feeders. The upgrade required new 12.47kV gear to be installed adjacent to the existing gear to minimize the downtime for the change-over.  Additionally, the installation included a new concrete equipment pad, primary and secondary feeders in underground duct banks and electrical connections to the existing overhead 12.47kV distribution feeders.


Our firm installed the SWGR on a weekend day to avoid disruption of power during normal business hours.  The campus shutdown and migration to the new SWGR was successful, and all project milestones were achieved to our customers satisfaction.

Key Services

This project included the design, procurement, construction, installation and testing of electrical equipment.

  • Pad-mounted 15kV Switchgear
  • 15kV Cable in underground duct banks
  • Acceptance Testing




Transform Power Equipment

Transform power equipment – a useful resource to save on expensive and unnecessary replacements

Transform power equipment instead of replacement which can save on costly expenses.  Your equipment may be working properly, but looks old and worn.  We apply engineering, testing and preventative maintenance skills to repair and/or recondition transformers, circuit breakers, switchgear and other electrical power equipment into first class condition.  Our testing skills are used to evaluate the condition and function of the electrical power equipment before and after restoration and energization.

We carefully evaluate the equipment and plan a customized approach for each customer.  Below are before and after photos of an outdoor padmounted transformer at a local campus, and a reconditioned circuit breaker for an industrial customer.  If your equipment looks worn and rusty due to wind and weather but still works good, we can refurbish it to look as good as new.  Our goal is to continue to help our customers be more successful.  Call us 717-252-4730 for a no-cost estimate to evaluate and restore weathered equipment.
