Frequently Asked Questions
What is governor in a generator?
A governor controls engine speed by regulating fuel delivery. Mechanical: flyweights acting on fuel rack. Electronic: speed sensor + ECU-controlled fuel actuator. Isochronous governor maintains same speed at all loads. Droop governor allows speed to decrease slightly with increasing load (necessary for paralleling).
What is a transfer switch?
An ATS (Automatic Transfer Switch) automatically switches load between utility and generator. Types: open transition (standard), closed transition (make-before-break, seamless), soft-loading. NFPA 110 Level 1 requires <10 second transfer for life safety applications.
What is AVR in a generator?
AVR (Automatic Voltage Regulator) maintains generator output voltage within ±1% of setpoint regardless of load changes. It senses output voltage, compares to reference, and adjusts exciter field current. Modern digital AVRs offer soft start, voltage matching, and Modbus communication.
What is wet stacking in diesel engines?
Wet stacking occurs when a diesel engine runs at low load (<30%) for extended periods. Fuel does not burn completely, creating carbon deposits on injectors, valves, and exhaust. Symptoms: black oily substance from exhaust, reduced performance. Prevention: load bank testing at 75%+ load monthly.
What is synchronizing in generators?
Synchronization is the process of matching voltage, frequency, phase angle, and phase sequence before connecting a generator to a live bus. Four conditions must match within tight tolerances. Auto-synchronizers (ComAp, Woodward, DeepSea) control engine speed and voltage to achieve sync conditions automatically.
How does a diesel engine work?
A diesel engine is a compression-ignition internal combustion engine. Air is compressed to high pressure and temperature, then diesel fuel is injected into the hot compressed air, causing spontaneous ignition. It operates on the Diesel cycle: intake (air only), compression, power (fuel injection + combustion), exhaust.
What is engine displacement?
Engine displacement is the total swept volume of all engine cylinders (bore x stroke x number of cylinders). Measured in liters (L) or cubic inches (in³). Example: Cummins QSK60 has 60L displacement. Larger displacement generally produces more power, but turbocharging enables smaller engines to match larger naturally aspirated ones.
What is Modbus?
Modbus is an open serial communication protocol widely used in industrial automation. RTU mode (8 data bits, RS-485) is standard for generator controllers. Registers map to generator parameters: holding registers for setpoints, input registers for measurements. Most controllers support Modbus RTU as their primary integration protocol.
What is genset derating?
Derating reduces generator rated output for environmental conditions. Factors: altitude (1% per 100m above 1000m), temperature (1% per 10°C above 25°C), humidity. For example: at 40°C and 2000m altitude, a 500 kW generator may only produce 420 kW. Always apply manufacturer's derating tables.
What is the difference between kW and kVA?
kW (kilowatt) = actual/real power consumed. kVA (kilovolt-ampere) = apparent power (real + reactive). The relationship: kW = kVA x Power Factor. For generators, 0.8 PF is standard: 100 kVA = 80 kW. Always size generators by kW, not kVA.
What is a brushless exciter?
A brushless exciter eliminates slip rings and brushes by using a rotating rectifier assembly. The exciter stator produces AC, which is rectified to DC on the rotating assembly, feeding the main rotor. Benefits: no brush maintenance, no carbon dust, suitability for hazardous areas. This is the standard for modern generators.
What is an alternator vs generator?
Technically: alternator produces AC, generator produces DC. Colloquially, 'generator' refers to the complete genset. Alternator components: stator (stationary windings), rotor (rotating field), exciter (provides DC to rotor via brushless excitation). Modern alternators are self-excited brushless synchronous machines.
What is CAN bus J1939?
J1939 is the SAE standard for CAN bus communication in diesel engines. Uses 29-bit identifiers, 250 kbps data rate. Standardized parameter groups (PGN) define data: engine RPM (PGN 61444), coolant temp (PGN 65262), fuel rate (PGN 65266). Primary communication between engine ECM and generator controller.
What is IP rating?
IP (Ingress Protection) rating indicates enclosure protection against solids and liquids. IP44: spray water protection, standard outdoor. IP54: dust protected + spray water. IP65: dust tight + water jets. Generator enclosures typically IP44-IP65. Marine/military may require IP66-IP68.
What is a heat exchanger?
A heat exchanger transfers engine heat to a secondary cooling circuit (often a cooling tower or raw water). Used in marine and stationary applications where direct radiator cooling is impractical. Shell-and-tube or plate type. Secondary circuit must handle the engine's total heat rejection.
