🧰 What Is Insulation Resistance Testing? Insulation Resistance (IR) testing is a fundamental, non-destructive diagnostic method used to assess the quality of electrical insulation. This is commonly performed on cables, transformers, motors, and switchgear. A megohmmeter (or “megger”) applies a high DC voltage to measure leakage current, which is used to calculate resistance (R = […]
Whether you’re commissioning a new facility or maintaining critical power infrastructure, NETA acceptance testing serves as a trusted benchmark to ensure your electrical system operates safely, efficiently, and reliably. At Electrical Test Tech LLC, we believe NETA standards are foundational to every aspect of electrical testing—from troubleshooting to preventative maintenance. đź“ś NETA’s Mission Statement “…to […]
What is SF6? It’s an inert, colorless, odorless and non-flammable gas.  Sulfur hexafuoride is about 5 times denser than air, meaning it’s heavier. If you were to fill a fish tank with SF6, you could treat the gas as if you were pouring water into a fish tank. It will collectively stay within the fish tank. It is […]
Before we can begin to talk about “Acceptance Testing”, you may or may not understand the phrase. Acceptance Testing pertains to all new electrical components. These are either purchased from a distributor, or even a manufacturer, but have never been put into “service”, i.e. energized. When a building is being remodeled, or even rebuilt, a […]
