Generator nameplates show electrical ratings that tell how much power the machine can give. These ratings include kVA, kW, and sometimes MW for big machines. Most commercial nameplates show both kW and kVA. The kW is usually about 80% of the kVA, because of the power factor. The engine size matches the kW, and the alternator matches the kVA. If you go over the kVA, the alternator can get hurt. If you go over the kW, the engine can stop.
Typical Generator Ratings | Example Values |
|---|---|
Small Commercial Units | 6.3 kVA (5 kW) |
Medium Units | 25 kVA (20 kW) |
Voltage Range | 208V to 600V |
Power Factor | 0.8 lagging |
Nameplates also show the kind of rating, like standby, prime, or continuous. Each one has different rules for how long it can run and how much extra power it can give. The table below explains these types:
Rating Category | Description | Run Time Limits | Overload Capability | Load Factor Limit |
|---|---|---|---|---|
Emergency Standby Power (ESP) | Maximum power during outages; no overload allowed | Unlimited during outage | No overload | 70%-85% |
Prime Power (PRP) | Power for unlimited hours in remote/rental use | Unlimited | 10% overload for short time | 70%-75% |
Limited-Time Running Prime (LTP) | Power for limited hours (peak shaving) | Up to 500 hours/year | No overload | Up to 100% |
Continuous Power (COP) | Continuous power for baseload applications | Unlimited | No overload | Up to 100% |
These facts help people pick the right generator and not overload it. Knowing the ratings and limits keeps things safe and working well.
Model numbers, serial numbers, and codes on nameplates help people know which generator they have. These tags show things like power, engine type, voltage, and build options.
The model and spec are on the nameplate. The spec is often a letter at the end of the model.
If the nameplate is gone, the serial number on the generator can help find the model and spec.
Giving the full model, spec, and serial number to a dealer helps get parts and manuals fast.
If there is no nameplate or serial number, a technician may need to look at the generator.
Code Segment | Meaning |
|---|---|
Model Number | Shows power rating, engine type, generator end, voltage code |
Build List Option Codes | Lists specific build options |
Spec Code | Identifies specification (often a letter) |
Serial Number | Indicates manufacturing date and location |
These numbers help with recalls and updates. Companies use them to find which generators need repairs. Owners can check their tags to see if their generator is part of a recall. This keeps everyone safe and records up to date.
Nameplates show frequency, power factor, and phase. These facts help match the generator to the right electrical system.
Specification | Description |
|---|---|
Frequency | Usually 60 Hz in North America, 50 Hz elsewhere. Some nameplates list both. |
Power Factor | Shown as PF, P.F, or cos φ. Standard is 0.8 lagging for industrial loads. |
Phase | Single-phase or three-phase. Three-phase systems have 120º phase difference. |
Frequency and power factor help make sure the generator works with the system. ISO 8528 rules set limits for voltage and frequency. These rules help the generator handle changes without breaking. The standard power factor of 0.8 lagging fits most industrial needs. Keeping frequency and voltage right helps the generator run steady, even with more than one generator.
Power Factor | Engine HP Impact | kW Output Impact | Amperage Impact | Explanation |
|---|---|---|---|---|
>0.8 lagging | Limited by engine power | Limited by engine power | Within rated amperage | Generator can supply rated voltage and amperage if engine supports the load. |
0.8 lagging | Ratings balanced | Rated output | Rated amperage | Standard for industrial loads. |
<0.8 lagging | Engine power sufficient | Limited by generator amps | Amperage may exceed rating | Output limited by max current, risk of overload. |
Phases tell if the generator gives single-phase or three-phase power. Three-phase generators can handle bigger loads and work more smoothly. People should check these tags to make sure the generator fits their system.
Tip: Always look at the nameplate before hooking up a generator. This stops problems and keeps equipment safe.
