1-Applicable procedures for calculating power and distribution transformer ratios, 2-Applicable procedures for calculating power transformer efficiency, 3-Applicable procedures for calculating power transformer voltage regulation, 4-Special Cases In Transformers Sizing Calculations: Secondary Unit Substations. Calculation of the Current Transformer 1MRS 755481 Accuracy Limit Factor 1. Scope This document describes the calculation of the actual accuracy limit factor (F a) for protection-type (P) current transformers (CT). First, the calculation of the actual burden of the CT, including connection wires and protection relay impedance, is presented. Download Free MEP Calculation Excel Sheets, AutoCAD Drawings, and Training Courses for HVAC, Firefighting, Plumbing and Electrical Systems Design. Spreadsheets for calculating fan requirements for the ventilation of electrical panels room and transformers. 10, equals 8760 unless for a special application/seasonal use transformer (irrigation, pumping) 11. 12, Capacity Factor. 13, = KWH sold per year through the. Design Parameters. For designing a transformer, we need: Power rating. Voltage levels (primary and secondary) Currents on both sides. Primary and secondary coils wire diameter/size. Then we proceed to calculate as follows:. Primary area(pa)= Primary turns(n1) / (Primary turns per sqcm). Secondary area(sa)= Secondary turns(n2) / (Secondary turns per sqcm).

Pad Footing Design Spreadsheet

This spreadsheet completes the design of single pad foundations including a central column. The column can include axial, horizontal and moment forces. The spreadsheet includes a simplified version for fast calculation of straightforward pad foundations.

Eccentric Footing Design Excel Sheet

This spreadsheet completes the design of single pad footings subject to eccentric loading. The spreadsheet allows the designer to position the column anywhere on the footing. The spreadsheet also allows the designer to analyse a footing of any polygonal shape including re-entrant corners and asymmetrical footings.

Combined Footing Design Excel Sheet

This spreadsheet completes the design of rectangular combined footings. The designer can analyse combined footings of any size with two columns placed anywhere on the footing. The columns can include axial, horizontal and moment forces.

Strap Footing Design Excel Sheet

This spreadsheet completes the design of strap footings consisting of two pad footings joined by a connecting structural concrete beam. The spreadsheet calculates the required sizes of both the pad foundations and for the connecting concrete beam. The spreadsheet calculates the bending moments and shear forces in the pads and the beam in order to design the required reinforcement.

Mat Foundation Design Spreadsheet

Microsoft toolkit and ez activator. This spreadsheet can be used to complete the design of mat foundations. The designer can analyse a mat foundation of any size including up to 32 columns placed anywhere on the foundation. The columns can be subjected to axial, horizontal and moment forces. The mat foundation can be analysed as either rigid or flexible depending on the size and thickness of the mat and the strength of the subgrade.

Design of Raft Foundation Spreadsheet

This spreadsheet can be used to design raft foundation subjected to a universally distributed loading. This is suitable for houses and small buildings with a raft foundation. The raft can be designed with a universally distributed loading and linear loads at the edges and corners of the raft.

Strip Footing Design Excel Spreadsheet

This spreadsheet completes the design of strip foundations including up to 16 columns placed anywhere along the strip footing. The columns can include axial, horizontal and moment forces making this spreadsheet suitable for warehouses and other buildings with column loads on long foundations.

Wall Footing Design Spreadsheet

This spreadsheet completes the design of long footings subjected to linear loads from walls. Arcsoft showbiz for mac download free. The spreadsheet allows the design to analyse a foundation of any length and width. The wall loads are a universal linear load per metre length of wall. This spreadsheet is suitable for house and small building foundations with wall loads.

Octagonal Vertical Vessel Foundation Design Spreadsheet

This spreadsheet can be used to design octagonal foundations such as those used for vertical vessels or pipelines. The spreadsheet can be used to design octagonal foundations of any size subjected to a single column load.

Beam On Elastic Foundation Spreadsheet

This spreadsheet can be used to model a large or long foundations which behave in a flexible rather than a rigid fashion. The spreadsheet models the system as a flexible beam supported by a Winkler foundation.

Soil Bearing Capacity Calculation

This suite of spreadsheets includes 9 different methods of analysing the bearing capacity of soils. The spreadsheet includes 6 different analytical methods including the Terzaghi, Meyerhof and Hansen methods. The suite also includes 3 different methods of estimating the bearing capacity of soils from site investigation results.
