A letter certifying that all facilities are complete and
functional, that each system is fully functional, and that each
item of equipment is complete, free from damage, adjusted, and
ready for beneficial use.
Cooling System
Certification that the engine-generator set and cooling system
function properly in the ambient temperatures specified.
1.3
SYSTEM DESCRIPTION
Each engine-generator set shall be provided and installed complete and
totally functional, with all necessary ancillary equipment to include air
filtration; starting system; generator controls, protection, and isolation;
instrumentation; lubrication; fuel system; cooling system; and engine
exhaust system. Each engine generator set shall satisfy the requirements
specified in the Engine Generator Parameter Schedule.
1.3.1
Engine-Generator Parameter Schedule
**************************************************************************
NOTE: Where multiple engine-generator sets of
different sizes or applications are to be provided,
a Parameter Schedule should be shown on the contract
drawings (one for each engine-generator set to be
installed). If only one engine-generator set is
provided (or multiples of the same type, size,
etc.), the schedule may be in the body of the
specification. Note that the specifications refer
to the Engine Generator parameter Schedule and the
designer must provide one each by that name.
Power Ratings and Industry Terminology. The
following definition is from the Electrical
Generating Systems Association Standard 101P, Engine
Driven Generating Sets. Stationary
diesel-engine-driven electric generator sets are
divided into the following four rating categories:
EMERGENCY STANDBY, LIMITED RUNNING TIME, PRIME
POWER, and INDUSTRIAL.
"EMERGENCY STANDBY RATING means the power that the
generator set will deliver continuously under normal
varying load factors for the duration of a power
outage". It must be understood that this definition
uses the term "normal varying load conditions".
Most manufacturers use this terminology to indicate
that their units typically are not rated for
continuous operation at the nameplate rating, but
rather that the units provided are rated for
continuous operation at 70% to 80% of their
nameplate rating, with periodic loading up to 100%
of the nameplate rating for short (cyclical) periods
during a power outage. Additionally, the designer
must analyze the load characteristics and profiles
of the load to be served to determine the peak
demand, maximum step load increase and decrease,
