GENERATOR FEATURES
• World Renown Stamford Electric Generator having UL-1446
certification.
• Full generator protection with Deep Sea 7420 controller,
having UL-508 certification.
• Automatic voltage regulator with over-excitation, under-
frequency compensation, under-speed protection, and EMI
filtering. Entire solid-state board is encapsulated for
moisture protection.
• Generator power ratings are based on temperature rise,
measured by resistance method, as defined in MIL-STD
705C and IEEE STD 115, Method 6.4.4.
• Power ratings will not exceed temperature rise limitation for
class H insulation as per NEMA MG1-22.40.
• Insulation resistance to ground, exceeds 1.5 meg-ohm.
• Stator receives 2000 V. hi-potential test on main windings,
and rotor windings receive a 1500 V. hi-potential test, as per
MIL-STD 705B.
• Full amortisseur windings with UL-1446 certification.
• Complete engine-generator torsional acceptance, confirmed
during initial prototype testing.
• Full load testing on all engine-generator sets, before shipping.
• Self ventilating and drip-proof & revolving field design
