There are two approaches to a Power Electrical Engineering Design. The first is to make the design so simple that there are no obvious deficiencies. The second is to make the design so complicated that it caters for each and every contingency and there are no obvious deficiencies. From every standpoint, the business, the project and the end user, the first approach is clearly preferable but it is far more difficult to achieve. Moreover, electrical engineers, through our training, our personality type and our experience, are generally predisposed to the second approach. Electrical cost and schedule blow outs despite the widespread use of best practice tools to monitor and manage variation.Difficulties in developing, maintaining and sustaining electrical safety awareness and focus.

EHAZOP, often referred to as SAFOP or an Electrical Safety Review (ESR) are a series of electrical studies that have been evolved over 20 years to help address this business need. The specific objectives an EHAZOP depend upon :

1. Client specific requirements
2. Project specific requirements (scope, complexity etc)
3. The timing of the study…FEED, Detailed Design, Procurement, Construction

1. Maximise design business value and minimise capital and operating cost
2. Alignment of electrical design principles with the business environment and project requirements
3. A critical review of electrical network design and electrical equipment and assess any limitations and their effects on operability and security.
4. Analyse electrical operator task, facilities and instructions and recommend measures to avoid operator error.
5. Systematically assess and minimise types of potential hazards presented to personnel in the vicinity of electrical apparatus.
6. Provide a structured forum for company personnel to ‘onboard’ construction and commissioning personnel and decide the form of interface arrangement most appropriate for the work, commercial arrangement and skills and experience level of third party personnel.
7. Engage end users in major electrical network and electrical equipment decisions.

Electrical System is the backbone of all the Industrial & Commercial Installations. Any disruption in the electrical system can bring the complete industry to stand-still and thus making it a highly critical part of any installation.

Electrical system can be very dangerous and lethal in case of,

• Incorrect designing
• Incorrect selection
• Incorrect Installation
• Improper Maintenance

Also industries need to comply with Statutory Govt. Regulations pertaining to Electrical Installations
