How to Measure External Earth Fault Loop Impedance. This video demonstrates external earth fault loop impedance testing using the MFT Pro from Test Instrument Solutions. This live test confirms the integrity of the supplier's earthing system and sets a baseline for future inspections. Before testing, we’ll cover key considerations, including identifying the earthing arrangement, disconnecting parallel earth paths, and ensuring safety protocols are in place. Watch as we perform the test step-by-s

Ever felt like the plane stops in the air just before landing? It’s called Ground Effect. Here’s what happens 👇 When a plane flies high, the wings push air down to create lift. But when it gets very close to the ground — the air gets trapped under the wings. That trapped air forms a cushion, like the plane is sitting on a pillow made of air. This cushion gives the plane extra lift, so it starts to “float” for a few seconds before touching down. For passengers, it feels smooth and magical. But f
