Why stones are laid in Substation?

  Reasons for using Stones in Electrical Switchyard & Transformer Yard: Stones in the substation is provided to reduce the step potential and touch potential when operators work on switch yard. Step and touch potential occurs due to the short circuit current flows on the conductor. All the substation is provided with the good grounding system or low resistance path to the fault current. Therefore to provide the high resistance for foot and ground, the stones are provided. Stones eliminate the growth of small weeds and plants inside the switchyard or transformer yard. It protects the moisture content evaporation and keeps the ground wet. Most in switchyard Power Transformers insulated with the insulation oil. The insulating oil spillages catches fire easily. So Stones/Gravel is provided to protect from fire when oil spillage takes place. Moisture on the floor level get minimised. Compensate the vibration in transformer which has been caused due to magnetostriction in core Improv...

What is Vampire Energy?

 If your electricity bill is unpredictable from month to month or it’s consistently higher than you would like, vampire power may be the culprit. What is Vampire Energy? Vampire power also called phantom power or standby mode, in which appliances consume energy even when they are shut off, can account for up to 20% of your monthly electricity bill. While sitting unused and idle, your TV or toaster oven is sucking money right out of your pocketbook. Why Do Devices Leak Energy? Essentially, every cord that remains plugged into an outlet is still using an electric current. While many devices have sleep or standby modes, they continuously use energy to perform updates, connect to remote servers, and record data. The connectivity of modern technology is one reason why devices leak energy. Even when the TV is off, for example, it’s still ready to receive a signal from the remote to power on at any time. Your DVR is always “lying in wait” until it’s time to record the next show or running...
