American Power Grid, LLC offers 24/7 Emergency services Nationwide to ensure that your Power System can get back up and running as quickly and smoothly as possible.  You can be confident in the fact that a project engineer manages every service that we undertake, even emergency situations.  

Load Tap Changer Retrofit (LTC)

LTC's have been historically impractical to retrofit due to varying flange lengths, lea configurations, operating mechanisms, and control differences.  Replacement require excessive downtime but the benefits out way the inconvenience.  LTC replacement or upgrade kits increase the reliability of your transformer at a fraction of the cost of a new transformer.  American Power Grid, LLC is able to provide the right mixture ofcustom engineering and field expertise to design, procure and install replacement LTC or to retrofit and existing LTC.  The benefits include:

  • Increased Transformer Life
  • Reduced Installation downtime
  • Reduced Maintenance Cost
  • Improved Reliability of Operation
  • Increased Contact Life Available
  • Reduced Costs as compared to Mobilizing Large Power Transformers

Circuit Breaker Retrofits (RTC)

Retrofiting of circuit breakers is often an extremely cost effective way to modernize existing switchgear while incorporating the latest technology into the system.  In most instances breakers can be mosified with little or no work required to the breaker cell components.    A well planned approach is the key to a successful upgrade. 

Transformer Oil Analysis

It is a well know fact that regular oil analysis/processing is useful in monitoring the condition of oil lubricated equipment.  This holds true when concerning transformers.   Transformer oil is used to insulate many transformers and electrical distribution systems.  The analysis of insulating oils provides information about the oil, but also enables the detection of other possible problems, including arcing, aging insulating paper and other latent faults.  Transformer oil analysis is an indispensable part of a cost effective electrical maintenance program.  By accurately monitoring the condition of the oil, suddenly occuring faults can be discovered in time and outages can potentially be avoided.  Most importantly, an effective approach to maintenance can be adopted and the optimum intervals determined for replacement.  Transformers are extremely expensive to replace regularly and must be properly maintained to maximize their life expectancy.  American Power Grid, LLC can take care of all your transformer needs from design, install, repair, maintenance and replacement.
