Capitalizing on its strength in core engineering services related to power projects, L&T-S&L has extended its service portfolio to include Transmission & Distribution Engineering Services for Utilities, IPPs and private power companies.
We offer T&D engineering services in the following areas:
Basic & Detailed Engineering Indoor/AIS/GIS
Protection and Automation Systems
Civil, Structural and Architectural
Load flow calculations
For full determination of voltage, active, reactive power, power factor and transformer control requirements as well as the verification of equipment ratings in the event of outages and faults in a power system
Reactive power compensation study
To improve power factor of the power system by suitably placing capacitor banks or other type of reactive power compensation device.
Short circuit calculations
Considering symmetrical and asymmetrical faults, for the verification of equipment rating, earthing requirement, fault voltages and current as well as equivalent connection point impedance.
Transient Simulation Study (In IEEE Format)
Determination of critical fault clearing time under different loading and operating conditions
Motor Starting Study (Static / Dynamic / Reacceleration)
To check for severe disturbances to motor, other locally connected loads and also to buses, electrically remote from the point of motor starting. The possibility of motor reacceleration under different contingency conditions, is also checked
Protection Relay Coordination
Protection relay coordination calculation and settings for identification of the most suitable settings for protective relays for various fault conditions so as to provide protection coordination to the plant equipment with optimum sensitivity, stability and selectivity.
Insulation Coordination Study
For selection of standard withstand voltages, which characterizes the insulation of equipment under study by checking the magnitudes of over voltages expected in the system due to different factors like lightning, switching, temporary overvoltage and very fast transients.
Ferro Resonance Study
Ferro resonance study for checking the configurations leading to unusual high voltages in the system because of Ferro resonance.
Arc Flash Study
Arc flash study to determine the flash protection boundary and the appropriate level of personal protective equipment during occurrence of electrical arc flash.
Various advanced software are deployed to enable accuracy and efficiency in our deliverable.
