Features :

A 'single line diagram' (SLD) is one of the most important drawing in a power transmission or distribution system. It shows the power flow in one line form. Three phases in AC system or two lines in DC system are represented by one line in SLD. In all our projects we are preparing such SLD. Over the years our engineers have gathered thorough experience in preparing SLDs for LV/MV/HV/EHV systems.

The SLD can be of two type - 1) Key SLD (does not show the CT and PT/CVT secondary circuits) and 2) Protection and metering SLD (shows details of protective relays and metering devices connected at the secondary sides of CT/PT/CVT).

Features :

Electrical layout plan and elevation shows location of different electrical equipment in switch yards and control buildings and also in plant electrical rooms. The drawing also shows clearances among various equipment, clearances with walls or building structures, clearances from mechanical equipment in the shop floor and maintenance areas for removal and overhauling of electrical equipment. Building dimensions (LxWxH) are decided on the basis of these drawings. Finalization of these drawings also allow designing of cable trenches, earthing systems, lighting and lightning protection layouts of the substation and electrical buildings. We can offer following type of electrical layout work.
