I. Introduction Electricity is an essential part of our modern lives, powering everything from our homes to our workplaces. However, dealing with high voltage electrical systems can be extremely dangerous, which is why it's essential to have qualified professionals who know how to work with these systems safely and effectively. High voltage electricians play a […]
Maintaining healthy sheath insulation is extremely important for the safe operation and lifespan of an MV cable. If there are faults in the outer sheath, you can expect an ingress of moisture, debris, and the premature degradation of the cables structure.
Power transformers are one of the most important pieces of equipment when it comes to electrical distribution. They are responsible for the transformation of higher voltages from distribution to lower voltages as seen in everyday electrical equipment. The most common type of transformer is the oil filled transformer.
Understanding the construction and operation of the circuit breaker is incredibly important, as they are used in nearly every installation from domestic buildings to high voltage electrical utility substations.
In most modern MV cables, especially underground, cables are shielded or screened with an earthing conductor. The screen consists of lapped copper tape or metallic foil usually less than 1mm in thickness, which is the interface between the conductor and the insulation (PVC, XLPE). The main purpose of this conductive screen is to maintain a uniformly divergent electric field and contain the electric field within the cable core.
Power factor correction (PFC) is an often-overlooked component in large electrical installations. It measures how effectively your business uses power by assessing the ratio of real power (kW) to apparent power (kVA). Real power is the amount of power which is actually used by your onsite equipment (kW) whereas apparent power is the total amount of power (kVA) supplied to the site by the utility.
Unexpected downtime can be an expensive. When an electrical fault occurs, it occurs rapidly, often resulting in major damage to electrical assets. This leaves your business inoperable and vulnerable to the costs associated with downtime and loss of production. By integrating an effective electrical maintenance program, you can ensure unexpected downtime does not happen. In […]
Underground high voltage cables are a great innovation to the electrical distribution industry. While they make an installation look more visually pleasing than the overhead systems currently being utilized, they are often exposed to scenarios which are overlooked by electrical designers and engineers. It is common practice to protect your cables from mechanical damage via […]
