Power quality is the ability of the electricity supply company to provide the networks and their consumers with optimal service without interruptions, surges, erratic equipment operations, voltage variations and deformations caused by harmonics in the network. Types of Disturbances In practice, electrical networks present a series of alterations or disturbances that alter the quality [...]
EVALUATIONS TO OPTIMIZE PERFORMANCE Fulfilling the promise of optimizing all operations in our clients' facilities, we offer solutions for energy quality analysis with results that guarantee the correct operation of all equipment. As the electrical quality is an indicator of the level of adequacy of the installation to support and guarantee an excellent operation [...]
Resistance - Resistance is measured in ohms (Ω). Resistance values can vary widely, from a few milliohms (mΩ) in the case of resistance between contacts, to trillions of ohms in the case of insulators. Most current clamps measure down to 0.1 Ω. When the measured resistance is higher than the upper limit of the [...]
What is a clamp meter? A clamp meter is an electrical tester that combines a voltmeter with a clamp-type current meter. The clamp meter is a very useful instrument specially designed to measure AC / DC currents that allows the measurement of currents in live conductors without the need to interrupt the circuit. It [...]
Limit the tension that metallic masses present with respect to the ground Provide the discharge point for the housings, frame or installations. Ensure that non-current parts, such as equipment frames, are always at ground potential, even in the event of a failure in insulation. Provide an effective means of unloading feeders or equipment prior [...]
In any electrical installation it is vital to take into account the importance of grounding. There are mainly two types of protections that depend on grounding in a basic way for their correct operation. These are protection against transient overvoltage (protection of equipment), and differential protection against indirect contacts (protection of people). The effects [...]
One of the challenges that companies continually face, especially those that carry out production processes that require a lot of energy, is the continuous increase in the price of electricity. This makes them progressively less competitive. And it is also one of the reasons, but not the only one, why there are more and [...]
Nobody expects a fire until it happens. That is why it is important to always be prepared to face it, since otherwise a fire in our company, factory or industry could be fatal. In addition, it must be taken into account that in industrial companies the risk of fire is greater. Especially in those [...]
Background: In the earlier Case Study, we saw how we solved a Transformer mal-tripping issue during our Routine Maintenance and Testing activities. We are presenting herewith another case which demonstrates why these activities should be entrusted to experts, who can make such routine jobs more meaningful and save assets. We were appointed to carry out [...]
Today, many plant managers operating in industrial companies, which account for 33 percent of total energy consumption in the United States, are somewhat anxious about having to follow programs like the one developed by the Department of Energy ( DOE). The US Best Plants Initiative requires corporate commitments to reduce the intensity of energy [...]
