Electrical studies for industrial systems

Short circuit, ANSI and IEC standards

Defines and verifies the capabilities of switchboards, switchgears and other electrical equipment to withstand short circuit faults without suffering loss of continuity in service due to catastrophic damage and/or repairs.

Short circuit studies can be developed in ANSI or IEC standards according to requirements.

Protective relay coordination, IEEE-242 standard

Its objective is to define the behavior of the electrical protection system to::

Allow start-up and full-load operation of protected elements.
Disconnect in the “minimum” possible time a circuit or element that has developed a short circuit fault and prevent the fault from spreading to other elements and with the least impact on the continuity of the operation of the electrical system

Arc Flash, IEEE-1584 and NFPA-70E standards

It is an electrical protection study whose objective is to determine the level of risk of burns due to an electric arc fault that a qualified worker who is going to develop work within a switchgear or electrical device that is energized, as well as the Personal Protective Equipment that should be used to control risk.

This type of study is carried out to comply with the standards:

1. IEEE 1584 – IEEE Guide for Performing Arc Flash Hazard Calculations.

2. NFPA 70E®: Standard for Electrical Safety in the Workplace®

Load flow and power factor, IEEE-399 standard

With this study it can be determined the operating voltage in the buses, visualize the distribution of power through the electrical system and the improvement of power factor.

Harmonic pollution control, IEEE-519 standard.

This study allows simulating current harmonic pollution from measurements, introducing solutions for the control of harmonic pollution and determining the results for the safety of the proposed equipment, the electrical system and the “resulting” harmonic pollution in an optimal way.
