Single Line Drawing Guidelines

05/08/2013 by 1 Comment

Overall plant single line diagrams show the electrical power distribution system, in simplified form, from the utility and/or generated supply to the load side of substation protection devices. Exceptions include substations 600 volts and over.

The size of the power system determines the number of drawings required.Generally, the overall plant single line diagrams do not include breakdowns of distribution panels, motor control centers, motors or similar electrical equipment located on the load side of the substation.

Single line diagrams, be it for a project or overall power system, show the electrical power distribution and utilization for a particular project, local plant area. read more

High voltage detector or indicator is the one of  important tool when perform the task in high voltage.It can determine if electrical line is live or not.The main purpose is to ensure we perform the job in a safety condition.

Around the world,many accident happened for electrical shock came from misidentified the electric line either it live or dead.Maintenance or electrical  person must double verify and confirm the electrical line status before do their job.

In the market now,we can choose many brand and types of high voltage ( HT ) detector.We must selected the suitable device depend on our application and system.

If we not sure how to used it,please request the supplier or technical expert to do a briefing and practical training how to used a high voltage detector.It very important because if not it can cause a serious damage for human and application. read more

When we need to perform Earthing or grounding resistance measurement,the important equipment that we must have is the Earthing resistance tester.

We can found many types and brand of Earthing resistance tester in the market.It’s depend on our budget,requirement and application on actual work site.We need to ensure this device must always calibrated to get the accurate reading.

This equipment is used to measure the resistance ( ohm) of the earth.It is important to ensure that the electrical installation grounding system in accordance with the specifications and meet the earthing requirement. read more
