Factory Acceptance Testing (FAT)

Every unit undergoes rigorous operational validation at the factory before dispatch. Type-test certificates and project-specific FAT records are provided:
100% Block Load Step Testing: Transient response (voltage/frequency recovery) recorded via digital oscilloscopes.
Dielectric Validation: Megger insulation resistance testing of stator and rotor windings.
Hydrostatic Testing: Core pressure validation of the cooling system under maximum thermal expansion limits.
Safety Shutdown Simulation: Forced-failure verification of low oil pressure, high jacket water temperature, and overspeed relays.
Acoustic Mapping: 8-point decibel verification to guarantee compliance with the ≤ 68 dB(A) threshold.

FAQ

Q: Can this generator integrate directly with our existing building management system (BMS)?

A: Yes. The control interface natively supports Modbus RTU (RS485) and Ethernet protocols, allowing direct integration into hospital SCADA and BMS platforms without external gateways.

Q: Are the seismic prints and structural weights certified for local code approval?

A: Yes. Every unit includes site-specific as-built drawings, structural wet weight calculations, and certified seismic anchoring prints to facilitate local engineering and regulatory sign-off.

Q: How does the generator protect sensitive digital lab equipment from voltage fluctuations?

A: The independent Permanent Magnet Generator (PMG) excitation system isolates the voltage regulator from load-side distortions, maintaining <3% THD and preventing voltage sags during heavy equipment cycling.
