ian Electricity Rules and other relevant standards. In case the Tenderer is not in position to comply fully with certain IEC/BIS specifications, or in respect of certain items for which there are no IEC/BIS specifications, the Tenderer may base his proposals on other reputed national international standards . 3.0 SCOPE OF WORK Scope of work for Electrics of ompressor Motor includes the fo llowing: ) 6.6kV HT VCB CICO Panel with protection, metering & control dedicated for this drive system. This shall be utilized for integrated Drive transformer protection and start/stop control of Compresso motor through Air cooled MV VF . The configuration of the panel shall be Cable in Cable out (CICO) aving two verticals. DC control supply for this panel shall be derived using suitabl rated capacity DC Power pack or DC power supply tapped from DCDB. ) Dry type, Indoor duty, Integrated Drive transformers (at 6.6 kV Primary Voltage) for Air cooled MV VFD drive. Secondary voltage shall be selected matching with VFD. This Transformer will be placed inside the anel along with Drive Lineup. ) Air Cooled MV VFD drives(in IP-5 enclosure) suitable for Compressor application with minimum 1 pulse or above configuration. It is preference to have 6.6 kV Motor and accordingly drive output voltage as 6.6kV.Driv shall communicate on Industrial Ethernet based comm unication (Profinet/Ethernet IP/Modbus over TCP-IP) with Plant Automation. & PLC system Accordingly necessary hardware shall be inbuilt in the drive. It shall provide all the parame ters like peak transient voltage , rise time an dV/dt etc, which are essential to be taken care in the design of Compresso motor for matching with VFD. Tenderer should limit his harmonics to minimum possib le values so that IEEE-5-2 values for THD can be met effectively at plant le vel Point of common coupling (PCC). ) HT squirrel Cage Induction Motor matching with above VFD. Preferred Motor rated voltag
