Basic engineering services consisting of Site visits, Data collection, Preliminary discussion/Kick off meeting with Client, Design Basis Report, Basic Engineering drawings, Design calculations for Extra high/ High/ Medium/ Low voltage Electrical systems and equipment. Main activities under this category are as follows. Basic engineering covers Electrical, Civil, Structural, Mechanical, Controls & Instrumentation, Substation automation systems :
a. Design Basis Report (DBR) : A document created in the begining of a project to freeze the basic technical parameters and criteria on the basis of which design engineering activity will be guided.
b. Basic Engineering Drawings : Key Single line diagram, relay & metering single line diagrams of power plants/substations/industrial power distributin projects, breaker/disconnects/ground switch control schematics, HV/MV switchgear schematics and wiring diagrams, Electrical layouts consisting of equipment layout, switchyard layouts.
c. Design calculations : Grounding / shielding / lighting calculations, cable sizing & voltage drop calculations, breaker/transformer sizing calculations, Neutral grounding equipment sizing calculations, AC/DC auxiliary system sizing calculations including battery & charger sizing, short circuit force and insulator spacing calculations, sag & tension calculation and stringing chart, CT & PT sizing calculations, Relay setting calculations etc.
d. Software used : Autocad 2009/12/13, ETAP 7.0 and MS Office.
