Remarks

Prime power(PRP)

Prime power is defined as being the maximum power which a generating set is capable of delivering continuously while supplying a available electrical load when operated for an unlimited number of hours per year under the agreed operating conditions with the maintenance intervals and procedures being carried out as prescribed by the manufactures.

The permissible average power output, over 24h of operation shall not exceed 70% of the PRP unless otherwise agreed by the RIC engine manufacturer.

Emergency standby power(ESP)

Emergency standby power is defined as the maximum power available during a available electrical power sequence, under the stated operating conditions, for which a generating set is capable of delivering in the event of a utility power outage or under test conditions for up to 200h of operation per year with the with the maintenance intervals and procedures being carried out as prescribed by the manufactures.

The permissible average power output, over 24h of operation shall not exceed 70% of the ESP unless otherwise agreed by the RIC engine manufacturer.

Standard Conditions

Standard operating environment: ambient temperature is 5℃~40℃, the altitude is less than 1000m,the relative humidity is less than 90%(25℃), and there is no dust, sand dust, salt fog, mold, condensation environment, etc. If the operating environment exceeds the above requirements, please contact the factory and consult.

Ambient adaptability protection measures for alternators

Ambient type	Ambient description	Measures of protection
General Ambient	The air is clean and dry, the humidity is ≤90%, and the distance from the coastline is ≥ 30km; Non-industrial ambient (chemical splash, acid-base steam, corrosive environment, etc.)	standard configuration
Humid Ambient	The humidity above 90% or condensation occurs	Anti-condensation heating
Saltspray Ambient	Salt fog crystals are produced in seaside (< 30km from the coastline) or island Ambient	Anti-condensation heating;Spray three-proof paint on winding surface;Spraying epoxy protection for parts and structures.
Dust Ambient	The ambient where mining, building construction, desert Gobi or sandstorm occur	Improve the protection level of the alternator to IP44;Install filters.

If you need to use protective measures beyond the standard, please contact the factory and consult.

Special working condition

If the operating conditions of the generator meet the following conditions, please contact the factory and consult.

Multistage parallel operation
Grid-connected operation
As the main power supply, it runs continuously for a long time
The load includes a high power motor type load
Capacitive load
Special ambient such as high temperature, cold and plateau
