Effect of Actuator Upgrade
Trip system retrofit by replacing former mechanical trip device to reliable electric trip device can
Enhance credibility of power plant and reduce operating cost.
Governing system retrofit by replacing former mechanical governor to EHC System controlled by servo valve can enhance credibility of power plant and reduce maintenance cost.
