Frequently Asked Questions
What is a standby generator rating?
Standby rating: maximum power for emergency use, 200-250 hours/year max, no overload. Typical for backup applications. Also called Emergency Standby Power (ESP).
What is biodiesel?
Biodiesel is renewable fuel from vegetable oils or animal fats. B20 compatible with most diesel engines. B100 requires engine modifications.
What is a load bank test?
Load bank testing applies artificial load (75-100%) to exercise generator. Prevents wet stacking, verifies capacity, tests cooling system. Recommended monthly for standby units.
What is an alternator vs generator?
Technically: alternator produces AC, generator produces DC. Colloquially, 'generator' means complete genset. Modern alternators use brushless self-excited synchronous design.
What is AVR in a generator?
AVR (Automatic Voltage Regulator) maintains generator output voltage within ±1% by controlling exciter field current. Modern digital AVRs offer soft start, voltage matching, and Modbus communication.
What is a turbocharger?
A turbocharger uses exhaust gas energy to compress intake air, increasing engine power density 30-50%. Critical for modern high-output diesel engines.
What is NFPA 110?
NFPA 110 is the US standard for emergency and standby power systems. Level 1: life safety (hospitals, high-rise). Level 2: less critical. Defines transfer time, testing, and maintenance.
What is wet stacking?
Wet stacking occurs when diesel engines run at <30% load for extended periods, causing unburned fuel accumulation. Prevention: load bank testing at 75%+ load monthly.
What is a brushless exciter?
Brushless excitation eliminates brushes/slip rings using rotating rectifiers. Benefits: no brush maintenance, no carbon dust, explosion-proof — standard in modern generators.
What is generator derating?
Derating reduces output for environmental conditions. Altitude: -1% per 100m above 1000m. Temperature: -1% per 10°C above 25°C.
What is genset paralleling?
Paralleling connects multiple generators to a common bus to increase capacity, improve reliability (N+1), and enable maintenance without shutdown. Requires synchronization and load sharing.
What is synchronizing?
Synchronization matches voltage, frequency, phase angle, and phase sequence before connecting a generator to a live bus. Auto-synchronizers control speed and voltage automatically.
What is a transfer switch (ATS)?
An ATS automatically switches load between utility and generator. Types: open transition, closed transition (make-before-break), soft-loading. NFPA 110 requires <10 sec transfer.
What is a diesel generator?
A diesel generator converts the chemical energy in diesel fuel into electrical energy. It consists of a diesel engine (prime mover) and an alternator (generator) mounted on a common base frame.
What is common rail injection?
Common rail maintains constant high fuel pressure (up to 2500 bar) with electronically controlled injectors. Benefits: precise timing, better atomization, lower emissions, 5-8% fuel savings.
