The rated voltage ratio of the transformers at no load normally is specified at 50 Hz, this being related to the principal tapping of the transformer. Tapping shall be provided on the primary winding to provide a ratio variation of +7.5% and –2.5%
Transformer winding resistance is very important factor for the life of any transformer, this test is part of type tests, routine tests and field tests. The purpose of winding resistance test is to determine the following: Calculation of the I2R losses in transformer. Calculation of
On this page you can find permissible limits for different equipment’s which are part of a power distribution electrical substation. Also where available reference to the international standard is also available in last column. Typical values are provided for transformers, reactors, circuit
What Are Cable Trays? An assembly of units/sections with associated fittings that form a rigid structural system to securely fasten or support cables. Think of a roadway bridge that supports traffic. Cable Tray Systems must provide protection to life & property against
Installation of capacitor bank shall be carried out in accordance to project specifications and approved drawings and technical submittals etc. Installation will be carried out by skilled and suitably experienced electricians under supervision of highly competent site supervisors and engineers to ensure
To protect cables from physical damage and the environment, store indoors and protect from moisture, construction equipment, falling objects, chemical spills, moving vehicles, and other hazards. When the cables are received inspect the protective covering on the cable for evidence of shipment
