NEC Has Proven Solutions to the Design Issues Documented in
OEM TILs, OMMs & AIBs
National Electric Coil's Specialized Engineering Solutions™ (SES) were developed to provide our customers with proven design solutions that would proactively address well-known generator problems. Each SES provides an overview of NEC's design and repair or retrofit appraoch. Because NEC has no vested interest in the original design, we can provide our customers with a more fully optimized solution. Below are links to SES documents addressing some of the more common problems.
NEC's Specialized Engineering Solutions™
Stator Solutions
- NEC's Coil Ready Kit allows owners to jumpstart their planned outages.
- Our Spare Winding solution provides insurance against unplanned outages.
- The benefits of a Stator Core Restack can range from improved unit performance to prevention of an unplanned outage.
- Generator units known as WESTACs can be rehabilitated to eliminate a number of troublesome generic design issues.
- Stator End Turn Vibration can be a major problem with certain generator units.
Rotor Solutions
- A number of different GE turbogenerator units are experiencing Rotor Dovetail Cracking and Rotor Turn Migration (GE TIL 1292) problems. NEC's Specialized Engineering Solutions™ thoroughly address both issues to provide permanent solutions.
In addition to our Specialized Engineering Solutions™, NEC also publishes Technical Maintenance Memos™ that provide genertor owners with information and advice on maintaining their units.
