Operation Verification, Maintenance Inspection, and Testing of Backup Power Supplies and Emergency Generators
We provide regular maintenance and anomaly diagnosis for emergency and standby power generators used in schools, hospitals, hotels, office buildings, underground malls, data centers, transportation, and telecommunications networks.
Overview
■ Rotational speed of the generator's crankshaft or flywheel is detected using gear sensors or electromagnetic pickups, and then fed into measuring instruments or signal converters to verify operation.
■ For parallel operation setups, our systems provide feedback to each generator unit to ensure accurate synchronization control.
