  • 5 Ideas to Start on the Path to Energy Efficiency

    Although most households use electricity on an ongoing basis, the industrial sector consumes the majority of the electricity used in the United States. Any industrial facility has the potential for using massive amounts of energy. Those that use the most tend to be industries such as glass, mining, petroleum refinement, metal casting, forest products, chemicals, aluminum, and steel. The process begins with energy coming from an outside resource. Energy produced is from off-site power plants, such as those that use: Steam Electricity Coal Natural gas And other types of f

  • Do You Know How Damaging an In-Rush Current is?

    There are many potential problems when operating electrical devices at your place of business, including electric motors. Correcting any issues that exist can help to save money, reduce the amount of energy that you are using and limit the possibility of unexpected equipment failure and the downtime that goes along with it. One issue that damages electric motors is in-rush current. Problems with In-Rush Current Other terms for in-rush current include switch-on surge or input surge current. It is relatively descriptive of the problem. In-rush current occurs when a motor is first energi

  • 34 Symptoms of Problems PdM Solves

    How many times have we ignored the "Service Engine Soon" dashboard light as we have driven down the road? The problem may be something as simple as a five-minute adjustment. As soon as we turn the car off, we forget all about the light. Eventually, ignoring the problem does not mean it goes away; it just means that five-minute adjustment changes into a massive repair bill. Your expensive equipment does not have a "Service Soon" light to let us know something is wrong. As a matter fo fact, sometimes we discover the problem after the smoke has cleared. Avoid these situations by implemen

  • Do You Know the Long-Term Benefits of Vibration Analysis?

    Your facility is an important investment, which is why you should make it a point to keep your equipment in check. Knowing the condition of your equipment helps ensure its excellent condition and prevent costly repairs. As any responsible owner, you need to maximize uptime through periodic monitoring of your machinery. This regular monitoring is what vibration analysis is all about, and industrial plants should incorporate it as an essential part of asset maintenance. What is Vibration Analysis? Although we have written about vibration analysis before, here is a brief review. [capt

  • How can the Power Factor Help Your Facility?

      In a perfect electrical system, we would get as much power out of it as was going into it. This results in the best case scenario, both operationally and financially. In reality, there are a number of issues that results in a reduction in the effectiveness of how power is used. Correcting those issues creates the have the most efficient system possible. There are a number of factors to consider in this regard. First, there is the KW or working power. This is the power that enters into the equipment. You also have KVAR, also known as reactive power. This is the power that it n

  • Transformers are the Key for Safety in Any Electrical System

    If you're working with any electrical equipment, you need to consider all of the components involved. The proper installation and maintenance of those components helps keep the working environment safe. It also extends the life of the equipment that you are using. Although considering many different components, any electrical system is going to need a transformer somewhere in the line of power. The transformer may take on some different forms. In essence, it is a device used to transfer energy between two circuits or multiple circuits. They are put in line to reduce the voltage that com

  • Why Online Motor Testing is a Great PdM Tool

    When correctly installed in the correct application, electrical motors fill a particular need. If well cared for; they can operate safely and economically for many years. In fact, they were designed to work indefinitely. But in most cases; issues are going to occur that need to be addressed. After all, we may operate the motors in a facility that subjects it to any number of different environmental, or operational problems. This could place stress on the motor and potentially, result in motor failure. When the electrical systems fail at our place of business, regardless of whether it is

  • A Quick Peek at Variable Frequency Drives

    Variable frequency drives (VFDs) are capable of using motor input frequency and voltage to control an AC motor’s torque and speed. When using variable frequency drives in applications ranging from small appliances to large-scale mining machinery,  substantially increase a motor’s energy efficiency, ultimately leading to considerable cost savings. For some businesses, the devices may eventually pay for themselves. However, despite this, their overall market penetration is still relatively small. For many industrial facilities, this means that there’s a significant opportunity f

  • Why is Short-Circuit Current Rating Important?

    There are several problems with electrically powered equipment. One of them is a short-circuit. However, prior to 2008, a there was no definition of a short-circuit current rating in the NEC. Since implementing the new guideline, it is important to verify and at times, improve the short-circuit rating to remain in compliance. The Article 100 of the NEC definition of a short-circuit rating is: "The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected without sustaining damage exceeding defined acceptance criteria."
