Electric Motor Protection Relays Explained

Single phasing, Earth faults, and short circuits are just a few potential points of failure in motors. Electric motor protection relays can help.

No facility wants to halt production due to an Earth fault or short circuit, but these things do happen. Still, you can prevent these shutdowns by using electric motor protection relays. That said, not everyone understands the intricacies of these useful devices. Read on to discover an explanation of electric motor protection relays.

Why Is Motor Protection Important?

The vast majority of motors in any given industry are induction motors. They are economical and easy to maintain, but they do require certain technology to run optimally and without failure. When you operate these motors without motor protection, you open yourself up to all sorts of financial risks.

In addition to the cost of repair or replacement, you’ll also lose money from shutting down production. Because induction motors are vital to your facility, you won’t be able to get back up and running until you fix the problems. You’ll lose precious hours fixing the problem, taking your employees away from other important tasks.

How Motor Protection Relays Work

You might wonder how motor protection relays work to solve this problem. They protect against short circuiting, thermal overloads, locked rotors, single phasing, and Earth faults. Once the relay detects a fault, it will open the breaker to disconnect the faulty circuit. Motor protection relays can also notify you when this occurs so you can get your people on it right away.

Benefits of Motor Protection Relays

This process avoids the potential of a motor functioning at limited capacity until it breaks, giving you time to address the problem as you see fit. By using an electric motor protection relay, you should not need to replace your motors. Instead, you can perform small repairs on the faulty circuits.

When you need GE Multilin relays for your facility, AX Control has you covered. We carry the products you need for your industry, and you can always reach out to us with any questions you may have.

Now that you know how electric motor protection relays work, you should have a better understanding of whether you need one in your facility. Make sure you look over the benefits of motor protection relays carefully. They can save you a lot of time and money.

Common Applications of Gas Turbine Control System

Without proper governance and control, gas turbines would be too much to control. Learn about the applications of gas turbine control systems today.

Gas turbines are marvels of technology, but what good is incredible tech without a way to control it? If your facility uses gas turbines, you likely also make use of gas turbine control systems. However, the control systems don’t get the same amount of love as the turbines, even though they’re essential to operation!

Read on to learn more about gas turbines and some common applications of gas turbine control systems.

What Is a Gas Turbine?

Gas turbines are complicated machines with three main sections: a compressor, combustion system, and turbine. The compressor is responsible for pulling and pressurizing air into the engine. This air is then fed into the combustion system, where fuel mixes with the air.

When this mixture burns, it produces gas at a high temperature and high pressure. This gas enters the turbine, causing it to spin and rotate the turbine blades. Finally, these blades cause a generator to spin and create electricity.

Gas Turbine Control System

While the gas turbine does all the work, the gas turbine control system keeps an eye on all the processes and maintains steady temperatures and pressures. The system also changes the fuel flow up or down to maintain a steady turbine speed.

Applications of Gas Turbine Control Systems

While the applications of gas turbines reach into chemical plants, refineries, and electricity generation, the uses of gas turbine control systems are far simpler. These systems do exactly what their name suggests—control gas turbines. This involves control of several temperatures, including the lube oil temperature, turbine temperature, and exhaust temperature.

In addition, control systems also monitor and regulate the fuel gas and air intake pressures while controlling the flow of fuel gas. Control systems must also have the capability to detect gas and flames in the enclosure for safety purposes.

When you need Woodward industrial controls, come to AX Control. We have equipment in stock, along with a helpful team to answer any questions and address any concerns.

Now that you know the common applications of gas turbine control systems, make sure your facility is equipped with the best technology. At AX Control, we have the industrial controls you need to keep your facility running smoothly.
