DESCRIPTION:The transition from commutator‑type DC exciters to brushless 
 excitation systems in the mid‑1980s marked a major advancement in genera
 tor reliability by eliminating carbon‑dust accumulation\, sparking\, and
  frequent maintenance associated with brushes. Between 1990 and 2010\, hun
 dreds of brushless exciters were designed\, manufactured\, and deployed by
 BHEL across Indian power plants and industrial stations. Today\, more than
  half of these units have already crossed their intended service life\, an
 d the remaining fleet is rapidly approaching end‑of‑life.\n\nField stu
 dies by MRTG engineers reveal a concerning pattern: many of these ageing e
 xciters are operating under harsh conditions\, with inoperative or mismatc
 hed diodes\, severe contamination\, degraded insulation\, corroded hardwar
 e\, and weakened mechanical assemblies. These issues\, if unaddressed\, po
 se significant risks to generator reliability and plant availability.\n\nT
 his webinar aims to build awareness among utilities\, industries\, and mai
 ntenance teams about the typical failure modes observed in legacy brushles
 s exciters and the urgent need for structured condition assessment\, maint
 enance and refurbishment. The session will highlight how MRTG—supported 
 by former BHEL generator experts—provides OEM‑equivalent diagnostic se
 rvices\, refurbishment solutions\, and reliability restoration for these a
 geing systems. Case studies will illustrate successful refurbishment of di
 ode wheels\, PMGs\, rotating rectifier assemblies\, and associated compone
 nts.\n\nThe talk will also cover MRTG’s in‑house manufacturing capabil
 ities\, including power diodes\, fuses\, RC blocks\, stroboscopes\, multi
 ‑contact pins\, DC ring assemblies\, PMGs\, and PMG magnet assemblies—
 ensuring continuous support to customers with components built to OEM stan
 dards. Preventive maintenance practices\, condition‑based monitoring\, a
 nd recommended inspection intervals will be discussed to help users extend
  exciter life and avoid forced outages.\n\nThe session will additionally p
 resent MRTG’s collaborative work with JNTUA academic institution on diod
 e failure mechanisms\, offering deeper insights into reliability engineeri
 ng for excitation systems. This webinar is intended to equip asset owners 
 with practical knowledge\, actionable maintenance strategies\, and confide
 nce in managing their ageing brushless exciter fleet.\n\nCo-sponsored by:
