[Selection Guide] How to choose the most economic size and type of cable?

Selection-Guide-How-to-choose-the-most-economic-size-and-type-of-cable

​Cable selection is about choosing the appropriate type of conductor and selecting a suitable size/cross-section area/ diameter of the conductor according to the application. First, there is a need to understand the significance of cable sizing and selection. Then selection criteria will be discussed keeping in mind all the derating factors that might reduce cable ampacity. A law named Kelvin's law plays a vital role in the economic sizing of conductors, so it will also be explained here. Other than the size of conductor, different types of the conductor will be studied. Also, the cable shielding and insulation will be discussed at the end.

Why Snubber Circuits are Required for Transformer Protection?

Why Snubber Circuits are Required for Transformer Protection?

Switching Transients or Transient Recovery Voltages may occur in certain situations and events occurring frequently in normal operations of a MV or HV industrial or commercial Power System. They may not be fatal in their first occurrence but prolonged exposure to transients will reduce lifespan of power system equipment. They may also disturb the stability of the power system putting the entire installation at a risk of shutdown or failure of certain equipment.

Top 5 Advantages of Parallel Operation of Generators or Alternators

parallel-generator

As every field of life becomes more dependent on electric power to operate and grow, backup power systems, like generators, are playing a progressively vital role in guaranteeing uninterrupted supply of power. Generator selection greatly depends on the amount of backup power needed for a specific application. An application may need minimal supply of backup power to ensure uninterrupted functioning or it may need full power of the backup system. It is hard to find a generator that matches the application requirement exactly. This is one area where parallel generators can shine.

Surge Protection Devices — Types | Role | Importance

SURGE_PROTECTION_DEVICES

With the expansion of electric power in today's world, electrical power systems are exposed to many critical conditions like overvoltages and voltage surges due to lightning strikes or abrupt switching conditions. The main concern is the overvoltage condition which can cause major damage to the system's equipment. Therefore, it is necessary to install a device that guarantees protection from the condition where over or under-voltage occurs.

Simple Method for Basic Short Circuit Current Calculations

simple-method-for-short-circuit-study-calculations

In order to dig deep into the easy way to calculate the short circuit current calculations, we must first develop our knowledge base on the basics of short circuit analysis.

"A Short Circuit current analysis is used to determine the magnitude of the short circuit current which the system is capable of producing and compares the magnitude of the short circuit magnitude with the interrupting rating of the overcurrent protective devices (OCPD)."

Should You Open Energized Panel Covers?

electrical-panel-inspection-working-personnel

The practice of removing energized switchboard and panelboard covers when performing annual/quarterly/monthly maintenance has become a common place. De-energization cannot be stressed enough before all types of maintenance work on electrical equipment can be initiated. This is rarely due to the fact that the personnel are inexperienced or non-qualified for the job, but instead it's usually because of following the traditional method without question.
