Power surges are very common but can have lasting impacts on equipment that is essential to a business. ⚡ According to the Electrical Safety Foundation, 60-80% of power surges originate within a facility and often lead to symptoms such as circuit board failure, lighting failure, motor failure, or phantom equipment restarts. Common internal causes of power surges include the switching of electrical loads, such as during breaker operations or capacitor bank switching, and magnetic or inductive coupling from equipment like elevators, HVAC systems, and office electronics. 🖥️ Power surges can also be caused by external sources such as lightning strikes, grid and capacitor bank switching, or damage to power lines and transformers. The root cause and full extent of equipment damage caused by a power surge may not always be easy to determine. That's why it helps to get an unbiased assessment from a team of experts. 📄 At TechLoss, our engineers have years of experience dealing with all kinds of equipment. We can help you determine if the damage was caused by an internal power surge or something external like a lightning strike. You can count on us to confirm the facts, verify the costs, and provide our expert recommendation on the best way to return the equipment to pre-loss condition. Call us today if you need help with a power surge-related claim. 877-832-4567 (877-TechLoss) www.techloss.com #lightning #powersurge #equipmentloss

Understanding Different Types of Electrical Circuit Breakers When it comes to ensuring electrical safety, it's essential to use the right kind of circuit breaker. Here's a quick guide to four important types: 1. Circuit Breaker (CB): The standard device for interrupting an electrical circuit during fault conditions, protecting the system from damage. 2. Miniature Circuit Breaker (MCB): Designed for protecting small circuits, MCBs trip during overloads or short circuits and are ideal for residential or light commercial use. 3. Earth Leakage Circuit Breaker (ELCB): This breaker detects earth leakage and prevents shock hazards, protecting both people and equipment from electrical faults. 4. Residual Current Breaker with Overload Protection (RCBO): Combining the benefits of an ELCB and MCB, RCBOs safeguard against both current leakage and overloads, offering comprehensive protection in one device. Choosing the right breaker is key to ensuring both safety and reliability in electrical systems.

Sunday FUNDAY - *"Step-by-Step Procedure for Safe Bus Charging in Electrical Substations"* Bus charging in a substation is a critical task requiring precision for safe operation. Follow this streamlined procedure: 1. *Safety Checks:* - Ensure all personnel are informed. - Verify protective relays, circuit breakers, and equipment condition. - Ensure the busbar is isolated and grounded. - Check insulation and faults. 2. *Voltage & Synchronization:* - Confirm incoming voltage and stability. - Ensure synchronization between sources and zero voltage difference. 3. *Breaker/Isolator Positioning:* - Open busbar isolators and circuit breakers. 4. *Grounding Switches:* - Close grounding switches to prevent voltage rise. 5. *Charge the Bus:* - Gradually energize by closing circuit breakers or couplers. - Prefer phased charging to avoid inrush currents. 6. *Monitor Parameters:* - Check voltage, harmonics, and currents. Open breakers if issues arise. 7. *Remove Grounding:* - Open grounding switches after confirming proper charging. 8. *Synchronize Load:* - Gradually sync and connect loads, ensuring proper synchronization. 9. *Monitor & Log:* - Monitor for abnormalities and log all data. 10. *Final Safety Checks:* - Verify all systems are stable and operational. *Key Safety Considerations:* - Always use PPE, communicate, and ensure only authorized personnel are involved. Safety and precision are paramount in bus charging to avoid risks.

In addition to our leak surveys, PCE also performs Electrical IR Thermography Surveys! Infrared Thermography is a noncontact and nondestructive way for detecting "hot spots", which are temperature differentials that may indicate problems in an electrical system. This survey can detect a problem before it manifests itself into a costly failure. Some benefits of this include: - Quick detection of problems without service interruption - Increased Safety and reduced fire risk - Significant reduction in unscheduled power outages - Minimized preventative maintenance and trouble-shooting time

Why Double Earthing is necessary for three phase machines? The electrical equipment enclosure earthed at two separate points with two separate earth pits provides the following advantages. When the electrical equipment enclosure is earthed at two points on the enclosure body, it establishes the two current path at the time of attaining of live potential. In the case of discontinuity of one circuit, the earth current keep on flowing through the other circuit and thus, the equipment remains fully protected against the earth fault. The two points earthing provides two parallel path for earth fault current. The two parallel path is connected to two separate earth points. Thus the equivalent resistance of the two parallel path gets reduced and it offers low resistance path to the fault current. If the resistance of one path is 0.4 ohms and the other path is 0.3 ohms, the equivalent resistance of the two parallel path is [(0.4 x 0.3)/(0.4+0.3)]=0.17 ohms. Thus the effective path resistance of the two parallel circuit gets reduced and it provides better reliable protection.

With the increased use of electrical devices during the winter, it's crucial to avoid overloading your circuits. Here are essential tips to ensure your business stays safe and operational: ⚡ Distribute the electrical load evenly by spreading devices across multiple circuits. ⚡ Regularly inspect wiring to ensure it’s in good condition and complies with safety codes. ⚡ Use power strips with surge protection to safeguard your equipment from electrical surges. ⚡ Limit the use of space heaters and avoid plugging multiple heaters into the same outlet. ⚡ Unplug devices that are not in use to reduce the load on your circuits. ⚡ Schedule regular electrical inspections with us to prevent potential issues.

Arch Flash is a hazard that often occurs to us when doing rack in/out activity (LOTO). Please find the video to prevent the Arc Flash explosions occur when substation personnel insert or remove (rack in or out) circuit breakers from low or high voltage switchgear cubicles. Here are a few that can be used to minimize the risk: - If possible, remove power from the gear - Review the proper procedure for racking in and racking out the circuit breaker for your specific gear which can be found in the manufacturers manual that came with your specific piece of equipment. - Make sure that our team understands the risks present prior to proceeding: 1. Incident energy level 2. PPE required while preforming this action 3. Where the Limited Approach Boundary and Restricted Approach Boundary are and to block off these areas  4. With easy to recognize barriers - Do not stand in front of the gear if we can avoid it - If we meet resistance while performing the action, do not force it - If possible, utilize a remote racking mechanism Rack in/out is not only the activity of removing and inserting mcb but we are faced with a HUGE ENERGY ⚡ that the correct procedure and execution are the main things that must be considered.
