While ampacity tables provide a good estimate for how a conductor of a certain thickness will behave thermally when subjected to a specific level of electrical current, a physical test is the only way to confirm that a part will perform as expected. Ensure that no damage has occurred between mechanical completion & precommissioning. 1. Testing and Commissioning is a quality-oriented process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria. Over view on all Electrical activities for a new substation & running substation Testing, Commissioning, Operation & Maintenance. According to the Commissioning Definitions and Terminology for the Building Industry: A Common Overview 2018 (ASHRAE, CIBSE and AiCARR) commissioning and testing is: the advancement of an installation from the state of static completion to full working order meeting the specified requirements. . This is all the concept of busbar protection. Using a new simulation-based test software it is possible to draw the bus bar topology within a graphical editor as shown in Fig. As a result, www.utilityproducts.com is using a security service for protection against online attacks. Electricalengineering123.com. Put the busbar protection out of service during this testthis means the buswires will be short-circuited and trip links will be opened. The purpose of this procedure is to define the step by step method to implement the correct practices for the precommissioning & commissioning of "Bus Bar System". REB611 is used in high-impedance-based applications within utility substations and industrial power systems. The commissioning process is a quality-focused process for enhancing the delivery of a project. The objective of testing is to provide confidence in the real-world performance of a part design. 323 0 obj

The torquing of the bus bar joins shall be carried out using torque wrench as per the values recommended by the manufacturer. Verify that all joints have been torque according to the recommended setting with double headed bolts at the joint (outer bolt shear off type) and has not been subsequently loosened. Ensure all tap offs are turned off again prior to energizing. Depending on the architecture, busbar protection may cross all zones in the substation. Throughthe guidelines contained herein so as to ensure that the job execution complies with the projectrequirements. When reconnecting the system prior to energization ensure correct phase rotation is achieved by testing prior to energizing the supply. Using a dynamic simulation software which directly controls multiple conventional test sets for simultaneous injection of test currents into all bay units is very efficient, since it does not require any rewiring all the time. hb```a``6c`c`} L@YR|pY:]9l7@Ezi1 )aTgdlp[` %i?S I'f18n-okPb#_/ N|2].v,Hy0m*S0 +
