Application Note EX-AMPLIDYN Highlights Basler’s Retrofit Solution to Aging Amplidyne-Type Excitation System

As capacity of generating units increased through the 1940s, turbine generator set manufacturers introduced new, continuously-acting voltage regulator/excitation systems that dramatically improved the response of generators during system disturbances. These continuously-acting dynamic amplification systems were known by trade names such as Amplidyne, mag a stat or Regulex”. They represented state-of-the-art excitation systems into the decade of the 1960s, with many such systems still in service.

Today, high maintenance costs and the diminishing availability of parts have made it difficult for owners to keep older equipment in reliable service. The purpose of Application Note EX-AMPLIYDN is to outline the solutions available from Basler Electric to help owners assure continued long life for the aging generation system.
