Information:

Generator Circuit Protection
The voltage regulator and related components protect the generator. All voltage regulators have fuses, which will stop the current flow to the exciter. No voltage is applied to the exciter. Therefore, the generator output voltage is reduced to a very low level. These fuses open very rapidly. This protects against secondary damage that is caused by another component failure. If a fuse is replaced, use only the same type and use only the same amperage rating. A larger amperage rating or a fuse that does not open rapidly will not prevent damage to other components. All voltage regulators have excessive current protection circuits. These current protection circuits are responsible for opening the excitation circuit.Note: For more information on the voltage regulation for 2600 series, refer to Service Manual, RENR2494, "K65-12B Voltage Regulator". For more information on the voltage regulation for 2400, 2500, 2800, and 2900 series, refer to Service Manual, RENR1246, "KCR-760 Voltage Regulator for SR4 HV".Generator Loading
When a generator is installed or when a generator is reconnected, ensure that the total current in any one phase does not exceed the nameplate rating. Each phase should carry the same load. This allows the generator to work at the rated capacity. If one phase current exceeds the nameplate amperage, an electrical imbalance will occur. An electrical imbalance can result in an electrical overload and an electrical imbalance can result in overheating.Block Loading
Block loading capability refers to the instantaneous application of an electrical load to a generator set. This load may vary between the rated load and a moderate percentage of the rated load. The block loading capability of a generator set depends on the following factors:
engine transient response
voltage regulator response
type of voltage regulator
altitude of operation
type of load
the amount of load during application of the block load If a block load derating is required, refer to "ISO 3046" or "SAE J1349 Standards". Also reference Engine Data Sheet, LEKX4066, "Block Loading Transient Response", and Engine Data Sheet, LEKX4067, "Transient Response".Power Factor
The power factor can be referred to as the efficiency of the load. This can be expressed as the ratio of kVA to actual kW. The power factor can be calculated by dividing kW by kVA. Power factor is expressed as a decimal. Power factor is used to determine the portion of current that is supplied to a system that is doing useful work. The portion of the current that is not doing useful work is absorbed in maintaining the magnetic field in motors. This current (reactive load) can be maintained without engine power. In most applications, electric motors and transformers determine the power factor of the system. Induction motors usually have a power factor of 0.8 or less. Incandescent lighting is a resistive load with a power factor of approximately 1.0.The power factor of a system can be determined by a power factor meter or by calculations. Determine the power requirement (kW) by multiplying the power factor by the kVA that is
