The Occupational Safety and Health Administration (OSHA) is an agency of the United States, Under the Department of Labor and was created by congress in 1971. OSHA is responsible for protection of workers including their health, safety at work, and managing heathy environment. In 1971, after the...

In this blog we will cover the Need of electrical grounding system, its importance, types of grounded system, common methods and the factors that effects the grounded system installation, safety tips etc. Simply, this blog is all about Electrical Grounding System.

The ground is the common...

Power flow, or load flow, is widely used in power system operation and planning. The power flow model of a power system is built using the relevant network, load, and generation data. Power engineers are required to plan, design, and maintain the power system to operate reliably and within safe...

Usually, a power system operates under balanced conditions with all equipment's carrying normal load currents and also the bus voltages inside the prescribed limits. This condition can be disrupted because of fault within the system. If the electrical fault current exceeds the interrupting...

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...

We have already discussed the importance of an arc flash study for low voltage equipment. You can read more about that blog by clicking here.

Though one might wonder, how big of an arc flash hazard is present in the case of medium voltage switchgear?

The answer: A LOT!

Before delving into...

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 Systems. They may not be fatal in their first occurrence but prolonged exposure to transients will reduce lifespan...

Under all circumstances, it is necessary to protect the working personal from dangers associated with live electricity installations. For this reason and to ensure compliance with the OSHA regulations, Arc flash hazard and electric shock hazards need to be evaluated and studied for every...

Have you ever wondered about the importance of an equipment maintenance plan and why is it necessary in Electrical power systems?

Today, we will talk in detail about the planned maintenance of electrical equipment and its importance. A maintenance plan covers a facility's routine maintenance, as...

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...
