How Does the Power Grid Work?
The modern world depends on electricity. It’s a crucial resource, especially in urban areas, but electricity can’t be created, stored, and provided at a later time. The instant it’s produced, it’s used no matter how far apart the producer is from the user. And the infrastructure that makes all this possible is one of humanity’s most important and fascinating engineering achievements: the power grid. -Patreon: http://patreon.com/PracticalEngineering -Website: http://practical.engineering Writing/Editing/Production: Grady Hillhouse Tonic and Energy by Elexive is licensed under a Creative Commons Attribution License Source: https://www.youtube.com/watch?v=U6fBPdu8w9U This video is sponsored by NordVPN.

How to pull a transformer DGA oil sample | Maddox Industrial Transformer
This step-by-step guide will show you how to pull an oil sample from your transformer. For more information on transformer maintenance visit: https://www.maddoxtransformer.com/news/should-i-repair-or-replace-my-transformer *For educational purposes only, should be performed by qualified professionals* To pull an oil sample from your electrical transformer for analysis: Step 1: Tank pressure is relieved First, the tank is relieved of pressure. Most transformers have an operating pressure of around 2 PSI. Before an oil sample can be taken the vacuum/pressure gauge must read 0. The gas sample valve is opened to relieve the pressure. Step 2: Purging the drain valve The cap is then removed from the sample port, and the drain valve is opened to purge any moisture, dirt, or other contaminants before sampling. Some people also recommend removing the drain plug on the end of the valve and cleaning it, just in case there are contaminates stuck to the back wall of the plug, but that’s usually not needed. Step 3: Preparing the syringe Sample syringes are provided by the laboratory performing the analysis. The valve on the syringe has 3 positions. Position 1: Closed to hose Position 2: Closed to bleeder Position 3: Closed to syringe With the valve in the “closed to bleeder” position, the sample can be taken. Step 4: Pulling the sample In this example, a small piece of plastic hose is used as an adapter to connect the syringe to the sample port. The adapter is also purged before the sample is taken. The syringe is inserted into the hose, the drain valve opened and the syringe is filled to a little bit over the 50cc mark. Step 5: Evacuating air from the syringe After the sample is pulled, the air in the syringe is evacuated With the syringe in an upright position, and the valve closed to either the bleeder or the hose, the plunger is pushed up, forcing the air and a little bit of oil out until the 50cc mark is reached. Step 6: Packing the syringe back up With the valve in the closed-to-syringe position, the syringe is wiped clean of oil, and packed for shipment to the laboratory for analysis. Step 7: Cleanup The sample port cap is re-attached, and the excess oil is disposed of per EPA guidelines. Step 8: Re-pressurizing the tank Finally, the tank is re-pressurized with nitrogen, and closed.

The Price of Complacency with Jason Brozen
Years on the job can build exceptional skill, but they can also create a dangerous illusion of invulnerability. In this episode of the LiveWire Podcast, host Asa Dyer sits down with Jason Brozen, CESCP, former master electrician, safety speaker, and arc flash survivor, to discuss the deceptive nature of complacency in the electrical trades and why seasoned veterans are often at the highest risk. Jason shares his personal journey surviving a catastrophic arc flash incident in 2009, how cutting corners on routine tasks changes lives forever, and why standard awareness seminars fail to produce truly qualified electrical workers. They explore the critical difference between theoretical compliance and genuine safety culture, the systemic underreporting of electrical burns, and how normalizing deviations puts entire teams in jeopardy.

What is a Battery Management System?
Have you ever wondered how a Battery Management System works? Erik Stafl, President of Stafl Systems, walks you through the basics, starting with two primary purposes of a battery management system for a lithium-ion battery pack: providing safe and reliable operation. Topics Covered: Purpose of a BMS BMS Inputs BMS Outputs Current Sensors BMS System Diagram BMS Communication The Battery Management System takes a number of inputs, including voltage, temperatures, and current among other inputs. The BMS then runs algorithms to create a series of outputs including state of charge (the fuel gauge), the state of health, the safe operating envelope ™, and any faults the battery pack may have. Erik then describes how the BMS is used in a multi-cell application, using a system diagram. Learn more at https://staflsystems.com.
