Alternator model Exciting model Insulation class Connection Cooling Structure type
1FC5456-6TA42 (SIEMENS) Brushless Class F 3-phase, 4-wire Air cooled AVR and reactive droop regulator assembled in alternator
 
(Kindly Noted: data shown in above table tested under standard working condition: 25 Dec C, atmospheric pressure 100kPa, relative humidity 30%, altitude <1000m.)

CONTROL PANEL

Control panel is panel type, vertical structure, model is GPL500. Control panel is equipped with meters showing various parameters of operating status, automatic air switch and timer. All of the electric cells possess three-proof functions.
 

The Generator possesses the following automatic monitoring and protective functions:


A) Audio or visual alarm for:
-  High oil and water temperature
-  Low oil pressure
-  Over current
-  Short circuit
-  Over-speed
-  Reverse power
B) Shut-off for:
-  Low oil pressure
-  Over-speed
-  Short circuit
-  Over-speed
-  Reverse power
C) Trip-off for:
-   Over-current
-   Short circuit
-   Reverse power
The generator can not only supply power directly to load but also can be paralleled running.

OPTIONAL DEVICE

♦ Steel Soundproof Container (sound attenuated canopy)
♦ CHP/ Cogeneration/CCHP Trigeneration
♦ ATS and Synchronization Parallelling Panel
♦ Oil and Water Heater
