Description

¿What does it solve?

Short circuit study

Short-circuit condition analysis in the plant through the use of specialized software. The loads that contribute to the fault or limit it are integrated.

To know what measures should be taken during the coordination of protections. What equipment should be installed and/or confirm that the magnitude of the fault is supported.

Protection coordination study

Verification of a correct detection and consecutive operation of logical order of the current protections. This is done through the use of specialized software

To know if the fault will remain isolated and will not affect other areas and processes, or if it has the potential to take the entire plant out of operation.

Arc Flash Study

Visualization of the equipment containing the highest amount of incident energy, using specialized software.

To know the security measures that must be taken to protect our employees and visitors according to security practices.

Annex IV

It is a series of files and DUs that contain technical information that is useful for CENACE and determines what steps the plant must follow to continue with its process.. 

Technical requirements that CENACE establishes as indispensable to develop a correct analysis.

Annex 3

It is a file that contains the technical information of the equipment inside the Electric Substation.

Necessary step to continue with the management process. 

Reagent compensation

Analysis, solution and implementation of compensation equipment that covers the totality of the client's needs, according to the power quality measurements obtained.

Depending on the proposed solution, it ensures compliance with the current Grid Code.

Load Centers

Existing

• With Change of Point of Interconnection.
• With Increases in Installed Capacity and that are interconnected.
• In Isolated Supply that requires interconnection and requires infrastructure for the delivery of surplus electricity (sale of energy).

• With increases in the Contracted Load and that are connected.
• In Isolated Supply requiring Infrastructure.
• Requesting a change of Connection Point.

New

• With Net Installed Capacity ≥0.5 MW and whether or not they require Infrastructure.
• In Isolated Supply that require interconnection and require Infrastructure for the delivery of their surplus electrical energy (sale of energy).

• With Contracted Load ≥1 MW or ≤1 MW, required to be connected and whether or not they require Infrastructure.
• In Isolated Supply requiring Infrastructure.
