ADEQUACY CALCULATION FOR PRIMARY EQUIPMENT RATING
Preparation of adequacy calculation for sizing of primary equipment rating such as current transformer and potential transformer,battery and battery chargers.Earthing calculation and lightning protection calculation etc. Our site co-ordination for the engineering works carried out by us for a project in Oman for the extension of a 132kV line.
Control and protection panel engineering,protection modification drawings,wiring diagram,control drawings for switchgears of MV,HV and EHV of Switchyard as well as GIS equipment,LCC,interface engineering and protection setting calculation for various protection system along with preparation of protection setting files for various types protection release and manufactures.
Preparation of protection modification drawings towards replacement of existing protection for upgradation,renovation of existing protection system.The various protection modification documents from existing to proposed arrangement are control room layout drawings,panel general arrangement drawings with bill of materials,detailed scheme drawings,Protection settings,adequacy calculation for CT/VT ratings,required control cable schedule etc.
WIRING DIAGRAM
Preparation of electrical connection
diagram enunciating the detailed
Integrated arrangement of panels and
system as whole
Marking of inter-connection points between various parts of the electrical drawings of a major electrical installation to facilitate the easy integration of different parts of the system during the execution of major electrical substation projects upto level of 765kV.
Includes system study for load flow analysis,short circuit analysis and relay co-ordination using etap software.Also protection setting calculation are being carried out.
Preparation of etap reports for load flow analysis,short circuit analysis and relay co-ordination.A major project fora petrochemical industry was carried out consisting of more than 50 mV switch gear substation as sub networks.
PROTECTION SETTINGS
Preparation of protection setting calculation for various types of protection and circuits to apply on the protection relays to commission the same.Experienced in preparation of protection settings for various projects up to 400 kV level for several inland and international projects.The protection setting files of different relays of different manufacturer can also be prepared enabling the commissioning of protection system easy.Preparation of etap reports for load flow analysis,short circuit analysis and relay co-ordination.A major project for a petrochemical industry was carried out consisting of more than 50 mV switch gear substation as sub networks.
“We have a well defined process which enhances our quality and accuracy and, at the same time, ensures timely responses, real time communication with clients and reduction in cost and turnaround time.”
We do site testing and commissioning services for various electrical substation projects.Our services include testing of primary equipment such As CT,PT,MV Switchgears,Switchyard LT panels,LCC and control and protection etc.All Tests will be carried our team with associated witness.All the test reports will be handed over to the client upon successful completion of site tests.
