Low Voltage Testing/Electrical Contracting Industry

The missing link in motor condition monitoring

Author - Mike Herring, Baker

Energy costs are a major part of the operating expenditure for any plant or facility, and in almost every case, electric motors are among the largest consumers of energy. Properly implemented monitoring of motor performance, which will help to improve reliability and extend the life of motors, is therefore an excellent investment, as it will reduce overall operating costs. 

To be truly effective, condition monitoring must include not only tests like vibration analysis, oil analysis and thermography, which mainly detect mechanical problems, but also a structured testing regime for electrical faults. All too often, other than the basic tests, electrical testing is deemed unnecessary. This is unfortunate, as studies have shown time and again that after bearing failure, electrical winding faults are the most common mode of motor failure. A structured electrical testing regime is, therefore, not simply an optional extra – it’s a vital requirement for achieving plant reliability.

Better Business: How The Pros Save Money & Time

AVO June Better Business

Owning your own electrical contracting business is worlds away from being an employee: the hands on work may look the same, but behind the scenes… well, there's a good reason it's behind the scenes.

Almost everyone is an employee before they are a boss. People who become business owners often do so because they love their profession and want more control; the action of running a business is an unfortunate consequence.

If the world were honest, business owners would tell you that running a company is like being a firefighter: racing around putting out fires. There is no solution to that problem because it's not a problem, it's the job description. 

How can you make your workday easier? Tighten up your business practices by staying organised and minimising distractions so you can put those fires out properly.

Take note of these tips, they will make your day as a contractor so much easier. You'll save money, stress less and find more time to enjoy your hobbies and family.

Getting To Know Electric Vehicles: Charging | Connector Modes

Charging Electric Vehicles

As environmental awareness drives technology to new heights, the electricity industry is seeing its fair share of the disruption. Electric Vehicles are just one of the rising technologies that we need to adopt, yet it is one of the most pressing.
