MAS S.A has both the background and the skilled team to retrofit automatic voltage regulators (AVR) and excitation systems for turbines and engines.

Many installed automatic voltage regulators (AVR) are at the stage in their product lifecycle when spares and support are no longer available. This component failure can result in loss of a generator.

We avoid this risk by offering proactive help with obsolete AVRs and excitation systems to prevent loss of power generation. MAS S.A has developed a range of retrofit and upgrade solutions, which focus on common obsolescence failure modes.

At MAS S.A we provide lifecycle support and retrofit services for your generator set to enhance reliability and reduce downtime. Our engineering team retrofits singular AVR systems as well as automatic voltage regulators which belong to larger engineered control systems found in various land and marine applications.
