Our studies

load flow

The purpose of the analysis is to determine the voltage and current levels in each branch for a specific condition of the System. Thus, confirm if the power flows are within the nominal capacities of the equipment.

Variables such as Power Factor, Active and Reactive Power Flow, network losses and Voltage at each node are determined.

The study allows calculating these parameters in different states of operation, and verifying the impact when there are changes in the configuration of the equipment or the electrical network. The applicable regulations are IEEE 399-1980.

short circuit

The purpose of the analysis is to calculate the magnitude of the currents when a fault occurs in the electrical network.

The study determines the equivalent impedance at a point of interest where an insulation fault of an element of the System will be simulated, and with this, the magnitude of the current will be calculated when a single-phase or three-phase fault occurs.

The Short Circuit current is applied for the analysis of the Interrupting Capacity. Each protection device must have the capacity to operate in a short-circuit situation without being destroyed.

The applicable regulations are ANSI / IEEE C37, NOM-001-SEDE-2012 and UL 489.

Coordination of protections

The purpose of the analysis is to determine the protection scheme against overcurrents in the electrical network, configuring the protection devices from the load to the source.

The study allows calculating the adjustments of the protection devices, the duration times and the trajectories of the fault to isolate it and not impact upstream in the electrical network. In this way, equipment and personnel will be protected.

Each device has a Time and Current Curve (TCC) that graphically represents the behavior of the operating current of the protections as a function of time. Maximum protection and continuity of service is intended, without the TCC curves overlapping, and when the overcurrent fault is isolated by the upstream protection that operates immediately.

The applicable regulations are NOM-001-SEDE-2012.

Electric arc

The purpose of the analysis is to determine the level of risk due to electric arc failure when activities are carried out in energized facilities.

The study makes it possible to calculate different parameters such as the magnitude and duration of the incident energy at a point of interest, and safe working distances. This information is printed on labels that will be placed on the boards and will reveal the risks of burns and electrocution, as well as the required Personal Protective Equipment.

The applicable regulations are NFPA-70E, NOM-001-SEDE-2012, NOM-017-STPS-2008 and NOM-029-STPS-2011.

harmonics

The purpose of the analysis is to evaluate the harmonic distortion of Voltage and Current caused by the presence of non-linear loads (for example: electronic ballasts, UPS systems, variable speed drives) in the electrical network. This phenomenon may cause malfunction or damage to electrical and electronic equipment.

The study allows dimensioning the capacitor banks for reactive compensation and passive filters to mitigate the effects of harmonics; also, identify and analyze the resonances to optimize the performance of the System.

The applicable standard is IEEE 519.

Network Code

As of the event in Red Eléctrica, which occurred on December 28, 2020, and the findings of the group of experts, the Grid Code has taken on paramount importance.

For this reason, at Baorgg we have given ourselves the task of offering a review service for compliance with the Grid Code. The focus of our service is the review of technical requirements for the interconnection of your Load Center.

Aware that the necessary experience can only be acquired using your hands, our work team consists of a group of engineers, with a broad and successful career at CFE, which brings together more than 250 years of experience.

Coupled with experience, we have the most advanced test equipment with a valid calibration certificate.

Power Factor

The power factor and its possible correction after carrying out a study is of the utmost importance for all electrical installations and load centers considering the widespread use of equipment driven by electric induction motors.



At Baorgg we carry out measurements in load centers with network analyzers to monitor and graph the behavior of Active Power (kW), Reactive (kVAr), Apparent Power (kVA), as well as voltage and current in the system.

Interconnection required by CENACE

CENACE carries out the Interconnection and Connection studies, which consist of different analyses, to determine the requirements to carry out the Interconnection or Connection as well as the needs for improvement or reinforcement of the National Transmission Network (RNT) or the General Transmission Networks. Distribution (RGD), to ensure compliance with Reliability Standards and Market Operating Provisions.

Electromagnetic compatibility

EMC is the ability of a system to not cause electromagnetic interference to other equipment, and at the same time, it must be insensitive to emissions that may be caused by other systems.

Based on the CEM, equipment for measuring signals and electromagnetic fields in both conducted and radiated modes has been developed. The purpose of these tests is to determine the level of electromagnetic emissions and the susceptibility to certain signals from electrical-electronic devices.

Land

Static Electricity is the electrical charges that are generated and stored in solid materials, particles or fluids. It does not represent a direct threat to life, however, an electric shock produced by a static charge can cause a startle and expose us to a risk, depending on the circumstances in which we find ourselves.

A static spark can have enough energy to ignite vapors and dust clouds.

Lightning rod

The purpose of a lightning rod system is to shield structures and their contents, for example: a building and people together with material goods, against a possible direct lightning strike. It is a mandatory requirement for Work Centers.



Its design must be carried out using the International Rolling Sphere Method, regardless of the technology of the lightning rod.

NOM compliance analysis

The legal framework under which electrical installations must be built is made up of the Public Electric Power Service Law and its Regulations, and the Federal Law on Metrology and Standardization and its Regulations,

Private electrical installations (“use”) are governed by Official Mexican Standards, the obligation of which is indicated in the aforementioned Laws and Regulations.



A significant percentage of accidents are due to electrical failures. The regulations applicable to the National Electric System (SEN) are not complied with by companies and organizations, however, it is mandatory, as it is published in the Official Gazette of the Federation (DOF).
