THERMAL IMAGING, POWER QUALITY AND HARMONICS

Thermal Imaging, Power Quality and Harmonics

February 4, 2016 — Infrared (IR) thermal imaging (thermography) is an effective troubleshooting tool, but many electricians who use IR cameras to spot overheated wires…

IMPORTANCE OF CIRCUIT BREAKER MAINTENANCE

Importance of Circuit Breaker Maintenance

January 8, 2016 — Reliability of the power system can only happen when proper maintenance is applied to the equipment within the system. The following applies to all classes of circuit breakers from molded case thermal breakers to 765kV SF6 Gas breakers. Maintenance consists of visual inspection of the mechanical operation plus electrical tests to verify the insulation integrity and operation of the breaker. The importance of circuit breaker maintenance cannot be overstated.

ARC FLASH COMPLIANCE

Arc Flash Compliance

December 1, 2015 — AVO Training Institute is a registered engineering firm and has conducted thousands of Arc Flash Studies all over the world. Our power systems uphold the original intentions of the NFPA 70E & Arc Flash Safety Awareness.

THE TRILLION DOLLAR CABLE QUESTION!

October 13, 2015 — A trillion dollars is likely a conservative estimate when you consider the magnitude of the power cable issues in the U.S.

A trillion dollars is likely a conservative estimate when you consider the magnitude of the power cable issues in the U.S. It has been known for some time that the cable systems in the U.S. have reached and in many cases exceeded their life expectancy. Let’s face it, wholesale replacement of an underground cable installation is expensive, time consuming and many times results in off hour scheduling and clearances requiring customers to be without power during reconnection of power to the installation.

KEEPING SAFETY TIPS TOP OF MIND

January 19, 2015 — Adherence to the following basic inspection and safety tips can help avoid serious — or even life-threatening — injuries while working with electrical equipment and systems. Important safety tips to help avoid injuries include, but are not limited to:

Electrical Cable and Maintenance Training | AVO

Electrical Cable and Maintenance — [pictured below, left] After careful planning, design and construction, AVO’s new state-of-the-art custom cable field was completed in 2017 and located in Dallas, Texas. It is designed to accommodate our updated Medium-Voltage Cable Fault Location & Tracing and new Cable Testing & Diagnostics courses; and it allows cable technicians the most technologically advanced “real world” place for every electrical cable testing and diagnostic application. With the critical issues facing the utility and industrial cable industry, it is imperative that training as well as test equipment technology be applied to existing and future cable installations to ensure ‘future proofing’ for improved cable reliability.

ULTRASOUND DETECTION OF ELECTRICAL ANOMALIES

Detecting Electrical Faults: The importance of process and the keys to effective testing — Knowing and understanding the different techniques used to detect electrical faults can give you the tools you need to avoid power outages, damaged equipment, and injuries. The article “Ultrasound Detection of Electrical Anomalies” in Plant Services Magazine discusses this important process and keys to effective testing.
