Technical Documents

This section contains all the technical documents that have been produced, with links that direct you to documents specifically related to the subject.

This section contains the Technical Information that addresses issues involving the definition of nominal voltages for systems and equipment, analysis of variations and admissible limits, evaluations and alternatives that can be adopted to minimize any problems.

This section contains technical information on how to calculate the three-phase short-circuit currents of an installation, easily and quickly, using the MVA method, without having to memorize formulas. In this section, the publication that gave rise to the newsletter is also available.

This section contains the technical information and the spreadsheet to calculate the secondary voltage of power transformers, depending on any type of load, primary voltage, primary winding tap, and impedance.

This section contains the technical information and spreadsheets to, based on the feeder data, calculate the load voltage when the source voltage is known or the required source voltage when the load voltage is defined.

This section contains the technical information with the definition of some criteria for the selection and sizing of load feeders, types of cables and their characteristics, as well as the spreadsheet to assist in this task.

This section contains the technical information that calculates the transient reactance of the alternator, in order to obtain a defined voltage at its terminals, for a given group of loads, and calculates the voltage at the alternator terminals, for a given load, when the alterantors data are known.

This section contains the technical information that defines the concepts for calculating the power of the transformers and the diesel emergency generator set.

This section contains the technical information and the spreadsheet to calculate the voltage in the generation of the Powerhouse of the plant based on data from the HV substation, step-up transformer and supplied power.

This section contains the technical information with the application of all documents published on the site.

This section contains the technical information with relevant information about the direct current systems of Hydroelectric Power Plants.
