Energy Analysis: Electrical System Evaluation

As utility costs rise, it's no surprise that energy efficiency is a priority for companies.

In a recent survey 25% of business leaders in the US listed energy as the greatest cost pressure for their businesses. Buildings are responsible for over 70 percent of the electricity consumption in the United States, approximately half commercial and half residential.

The amount of savings we can have in commercial buildings, especially where we can do a systems engineering approach, is staggering, perhaps as much as 80 percent reduction.
This is not low hanging fruit......this is really fruit lying on the ground!

Our approach at Brenco is to simply let your building tell the variables to take into account for every project! Our licensed professionals perform a comprehensive on-site electrical system analysis and evaluate your distribution systems to determine energy:

• Present Performance and future Requirements
• Consumption
• Power Flow
• Reliability
• Power Quality Measurements
• Power Factor Correction
• Demand Charges
• Losses
• Harmonics
• Conservation Opportunities
• Alternatives for System Improvements and Expansion
• Rebate Programs/Tax Incentives
• Value-added Engineering Services

Loads controlled by “nonlinear” electronic components are becoming more prevalent in both home and industry, meaning that the voltages and currents in the power system(s) feeding these loads are rich in harmonics: what should be nice, clean sine-wave voltages and currents are becoming highly distorted, which is equivalent to the presence of an infinite series of high-frequency sine waves at multiples of the fundamental power line frequency. Our engineers and technicians can precisely detect and measure these conditions plaguing your power system.

Anything other than a clean sine wave could be an indication of trouble

Excessive harmonics in an AC power system can overheat transformers, cause exceedingly high neutral conductor currents in three-phase systems, create electromagnetic “noise” in the form of radio emissions that can interfere with sensitive electronic equipment, reduce electric motor horsepower output and can cause energy costs to skyrocket.
