Why Protect Your Electronics?Īn EMP is one of the scarier survival events that preppers need to be ready for. This is why it’s important to unplug your electronics to protect them from EMPs, because pretty much anything plugged in is at risk of being ruined. Once the EMP event is over, this field rushes back to fill the area and introduces currents and voltages that can destroy the electrical grid. An EMP makes the Earth’s magnetic field temporarily get pushed out of the way. The final way an EMP can damage your electronics is because it creates a large surge of energy. You can use electromagnetic shielding to stop this. This can potentially destroy your electronics even if they’re inside of a Faraday cage by creating voltage between semiconductor junctions. The second way is because of an EMP’s high magnetostatic gradient. You can use a Faraday cage or bag to prevent this from happening to your electronics. An EMP can destroy semiconductors if its electrostatic gradient is high enough. The first is because of an EMP’s high electrostatic effects. How Does An EMP Damage Electronics?Īn EMP (electromagnetic pulse) can damage your electronics in three main ways. BATTERY PULSE TECK HOW TOIn this article you’ll learn how an EMP can damage your electronics, why you’d want to protect them, and how to go about it. Electronic items without microchips just need to be unplugged from the grid and they should be safe from any damage. Anything with a chip needs to be protected, or it may be damaged. How can I EMP proof my electronics? The most effective and easiest way to protect your electronics from an EMP is by using a Faraday bag. This enables maintenance, training and production staff to easily access, process and analyse the data on a shift basis, to identify where production shortfalls arise and where further operator training is required.Are you worried about how EMPs could affect your electronics, but you’re not sure how to protect them? We took a look at some of the precautions you can take. Data is saved in a SQL database and is accessible through an advanced server analysis programme located on the mine’s intranet. The system developed for Teck is configured to communicate through the mine wireless mesh to a server located in the mine’s administration offices. Productivity indicators provide meaningful online feedback to the operator including average bucket/truck payload, overall shift production, swing cycle time and operating and delay times. These transducers allow the system to track boom jacking and adverse swing events, identify alarm events and quantify the mechanical damage per swing cycle. Recent developments of the system have included a comprehensive machine health monitoring capability using strain sensing transducers placed on the A-frame and boom structures. Our system has now become the system of choice at Teck’s Greenhills operation and by delivering added value benefits to the customer we hope it will become the reference for other Teck operations.”Ĭonfigured to communicate with any third party truck dispatch system, the Pulse TerraMetrix RS system can be applied to different models of electric rope shovels including P&H 4100 and CAT 7495 machines. As a result, more accurate payload measurement is maintained, even under severe dynamic loading conditions. This includes one P&H 4100XPB and two P&H 4100XPC machines, one of which is currently being assembled.įollowing the final implementation of the Pulse TerraMetrix RS system on the P&H 4100 XPB in 2012, BMT TBM says that “Teck staff recognised the benefits of this innovative payload monitoring system together with its interactive server database, allowing personnel to easily analyse health, production and payload data.” Charles Constancon, Director of BMT WBM Canada explained: “Unlike other payload monitoring systems which apply electrical parameter estimation techniques to approximate the payload, the Pulse TerraMetrix RS system employs a loadcell based device and directly measures the inertial and dynamic loads applied to the dipper. BMT WBM, a subsidiary of BMT Group, is set to deliver two new Pulse TerraMetrix RS systems to Teck Resources. Machine health, production and payload measurement will be managed by the PULSE TerraMetrix System on the entire shovel fleet at Teck’s Greenhills coal operation near Elkford in southeast British Columbia, Canada.
