Cost-Effective Solutions In the field of electrical services, ensuring the optimal performance of equipment is crucial. Electrical transformers play a pivotal role in power distribution, and when they malfunction, they disrupt operations and lead to significant downtime. One strategic approach that has gained traction in recent years is outsourcing the…
How Transformer Testing Can Save You Thousands in Repairs!
Insights from a Professional Electrician In the complex world of electrical systems, transformers play a pivotal role in ensuring a steady and efficient power supply. However, like any machinery, transformers are susceptible to wear and tear, potentially leading to costly repairs. As a seasoned professional electrician, I’ve witnessed firsthand the…
Control Power Transformers in Switchgear II
Control power systems change the VOLTAGE levels of the primary voltage, to a usable level needed by many electrical devices. For instance, a common low voltage system (one thousand volts or below) operates at 480 volts, a popular distribution voltage in factories. 480 volt is used to power 480-volt three…
Electrical Disconnect Switches & Circuit Breakers
Electrical switches, used to disconnect/ connect power, have a mechanism to handle flash over current via arcing contacts. Arcing during load break is a normal phenomenon. It is a result of interrupting an electrical signal with significant energy. When two conductive surfaces begin to separate, the electric flow wants to…
Don’t Let Electrical Failures Ruin Your Day! Discover the Magic of Infrared Imaging Scans
In the realm of facility management, ensuring the safety and efficiency of large machinery and electrical systems is paramount. The cost of electrical failures, both in terms of downtime and repairs, can be astronomical. This is where the proactive strategy of regular infrared imaging scans comes into play. As an…
What Does A Transformer Repair Entail?
Sometimes during transformer infrared inspection or during a GA oil analysis problems are found. Elbow Problem Bushing Well Insert Problem If you don’t fix transformer issues found during your infrared inspection you might find yourself doing this! Transformer problem areas can include the following internal parts: HV Cable Loadbreak Insert…
Bolted Pressure Switches
REMEMBER: Just because you haven’t seen problems doesn’t mean there are no problems! These system’s do not announce failure. When called to operate, malfunction will put your facility without electrical power quicker than you can say “why didn’t I maintain this?”
