Power Cable Neutral and System Grounding

Installing medium voltage power cables underground comes with its own set of challenges. From an engineering standpoint, there are several factors one needs to consider before installing the cable. The most overlooked if not a well-understood factor is the type of power cable that’s required for the application and when to ground the cable’s neutral …

Substation SCADA System – Design Guide

For electrical engineers, designing the Supervisory Control and Data Acquisition system (SCADA) for an electrical substation can be a daunting task, if not confusing with the different ways you can connect various Intelligent Electronic Devices (IED’s) based on protocols each device supports. This article serves to help you understand this system so you can design one as well.

Cable and Conduit Installation in Substations – Best Practices

Substations contain equipment that are controlled by relays. If the relay is installed at a remote location such as a control house then you need to lay down wires from the relay to the location where the equipment is in the yard. The process of laying wires can be as simple as directly burying them in the ground to pulling them through a conduit. Sometimes cable trenches are used. Site conditions, project funding, and the type of substation (bulk power vs. distribution) dictates which method is the most suitable.

Why We Need Electrical Power Substations

We build substations for the following reasons: Practical Considerations To satisfy load growth When people or businesses move to a new location that has little to no power supply infrastructure, it might make a case for building a substation close to the community. Supplying this new load from distant substations is inefficient because a little …
