Variable Frequency Drives


Burlington Electrical Testing offers services for facilities that require maintenance and modifications of low-voltage and medium-voltage Variable Frequency Drives (VFD).

Variable-frequency drives, also known as adjustable-speed drives (ASD) and AC inverters, are widely used in HVAC systems, pumps and conveyors. A VFD controls the rotational speed of an alternating current (AC) electric motor by adjusting both the voltage and frequency of the electrical power supplied to the motor.

Servicing of Variable Frequency Drives compliments BET’s switchgear and motor testing and maintenance services. BET’s VFD field engineers provide expertise in diagnosing, troubleshooting, repairing and debugging drive systems.

BET serves facilities in the following industries: Airports and Aviation, Petrochemical, Colleges and Universities, Government, Utilities, Independent Power Producers, Co-Generation Plants, Electrical Contractors, Mechanical Contractors, Engineering Firms, Pharmaceutical Companies, Original Equipment Manufacturers, Municipalities, Data and Telecommunications Centers, Hospitals, Commercial Real Estate, Banking and Insurance, Military Installations, Nuclear Power Plants and Transportation.

For reliability testing, acceptance testing and certification, emergency troubleshooting and service, or system upgrades contact any of our BET representatives.


NFPA 70E 2021

Is your site NFPA 2021 compliant? Is your staff "qualified" or "unqualified" to work on electrical equipment?

Burlington Electrical Testing conducts onsite Arc Flash Hazard Awareness training which provides an understanding of the federal laws (OSHA), potential dangers, as well as the accepted safety practices when personnel are to be exposed to electrical hazards.

This includes defining an arc flash and its effects on the human body, complying with Arc Flash labeling, and the selection and use of Personal Protective Equipment (PPE).

The Arc Flash Hazard Awareness class is to be part of your overall electrical safety program; therefore, your staff will require a working knowledge of the electrical equipment at their facility, along with the tools, test equipment and available PPE.

The one day class is presented by an instructor certified by NFPA, and the NJACT / NECA to instruct Electrical Safety Related Work Practices based on NFPA70E 2018. Curriculum follows the accompanying Electrical Safety-Related Work Practices text modules and will focus on:

1. Electrical Safety Culture
2. Electrical Hazard Awareness
3. OSHA and NFPA 70E concepts
4. Electrical Safety Program
5. The Control of Hazardous Energy
6. Arc Flash Hazard Analysis
7. Personal Protective Equipment
