Some months ago, in a workday morning, I received a call from one of the engineers of a factory who owns a private substation adjacent to one of region electric company's substations which I work for. me: So, Sir, what's the problem?! him: That's a problem with your network and protection system which made the protection of the main transformer of our private substation to operate and tripped the CB. me: 😆 what the heck... when dear Sir? him: today after midnight. I asked from the dispatching center and they told me at the exact moment there was fault over one of the lines connected to the upstream substation which feeds ours. me: but dear Sir, there was a fault over transmission line near to our substation, it has not cause any operation of the protection relays of your side. him: but it does and I don't know how! is there any problem with your system which can affects our substation?! So... now let me tell you more with some details. here is a very abridge illustration of the mentioned network. the point of a phase to ground fault is shown and without any doubt you can identify it. The shown fault caused a trip command to the Q0 of private substation by Neutral over current protection of the 63 Kv side. him: does any earth fault cause to flow current form the neutral point of the transformer of our side? me: for sure. him: but why? me: the zero sequence of the down steam substation is in parallel with the zero sequence of fault's circuit. him: 😲 In the next posts I will provide more details.

What Is EHV Electrical Infrastructure? EHV (Extra High Voltage) electrical infrastructure refers to the network components designed to transmit electricity at voltages typically above 132 kV. This facilitates long-distance, high-capacity power transmission with minimal losses. Some key components and aspects of EHV electrical infrastructure include: #EHVInfrastructure #HighVoltage #PowerTransmission #EnergyNetwork #ElectricalEngineering #RenewableEnergy #SmartGrid#UtilityIndustry #EnergyEfficiency #GridModernization

As part of the rapid growth and development of the whole electric vehicle charging infrastructure, filling stations are seen as an obvious place to provide charging facilities. However, it is recognised that difficult safety and logistical issues are linked to such installations. This Code of Practice is an authoritative guide to all installations of electric vehicle charging equipment. It has been updated in line with recent changes in BS 7671 (IET Wiring Regulations) and reflects some major developments in this area including vehicle-to-grid, smart integration and inductive charging.

This week he covers Section 4, the determination of conductor ampacity for specific conditions of use, maximum conductor termination temperature, selection of a neutral conductor, and conductor identification. #electricalindustry #conductors

Have you ever wondered about the causes of over voltages in electrical power systems? Over voltages, also known as voltage surges, can have damaging effects on equipment and infrastructure. There are several factors that can lead to over voltages, such as lightning strikes, switching operations, and faults in the power grid. These events can cause a sudden increase in voltage, exceeding the safe operating limits of electrical equipment. By understanding the causes of over voltages, we can take proactive steps towards safeguarding our power systems and minimizing downtime. Let's stay knowledgeable and keep our power systems running smoothly!
