The commissioning procedure of substation busbars for differential protection and other busbar protection schemes involves a large number of input and output circuits that require a verification check in both the primary and secondary circuits. Customer handling and proper coordination with clients. The action you just performed triggered the security solution. Cloudflare Ray ID: 7a119f59ae508cd7 This test is performed by initiating a specific amperage through the test specimen and measuring the heat rise with thermo-couples. $>MSl%`6LM@8+X6"La`& Isolate the bus way run by disconnecting all connections to transformers, switchboards, meters, and so forth. Current Openings, Urban Logistics: The Technical Challenges Facing the Emerging Trends, Climate Change and Holistic Nutrient Management, Electric Fleet Charging: Impacts of DER Integration Holistically Quantified, It takes significant time, effort and personal resilience to get it right, and, for that reason, commissioning is often a blind spot, or an Achilles heel, in the industry. Throughthe guidelines contained herein so as to ensure that the job execution complies with the projectrequirements and serves the intended function to satisfactory level. Initially the bolt can be tightened with a standard spanner, if it has to be removed in future, the re tightening torque, using a torque wrench 50 60 ft pounds. All Rights Reserved. 1 0 obj hbbd```b``@$d"Y3@$0 &U*.30, The following test will be conducted as a standard on every run of busbar. REB611 is used in high-impedance-based applications within utility substations and industrial power systems. Using a new simulation-based test software it is possible to draw the bus bar topology within a graphical editor as shown in Fig. endstream endobj startxref www.utilityproducts.com is using a security service for protection against online attacks. Are the Horizontal supports for the busbar installed as per the installation manual standard? When 52-2 CT fully saturates, its magnetic field impedance is effectively 0.00. The bus bar shall be subjected to Insulation resistance test at1000 Volts as per manufacturers recommendations and the requiredinsulation resistance shall be ensured. Please enable cookies on your browser and try again. Ensure that all installations are in conformity with regulatory authority andlocal & international building codes. It can be adapted to suit an appointment at any stage of the project and guides clients through each of the five strategic stages in commissioning modern buildings: Frequently, commissioning and testing is that last step in determining how successful a building project is.

Ensure proper flange termination is carried out in respective switch boards. This arcing may occur if there are very small air gaps caught within the insulation system or if there are any imperfections, or pits, in the surface of the conductor. After initial verification by the Commissioning Manager, the PMCM will be invited to witness the works. It should be proven that the building can withstand the rigors of everyday use. 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. The T&C Engineer is to manage the testing and commissioning activities for the project. Only authorized, competent personnel should energize electrical circuits in line with switching procedure and permit to work forms provided by the site supervisor. 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. In modern commercial offices and data centers for example commissioning is a complex and highly technical process that requires considerable attention to detail and ongoing day-to-day, even hour-by-hour planning. Let's work together to make great things possible. Cloudflare Ray ID: 7a119f2aac11206a The test works by measuring the amount of partial discharge in Coulombs, also called arcing, between the copper or aluminum conductor and the insulation that is applied to the surface of the bus bar. Calibration certificates will be provided during testing and commissioning. This is all the concept of busbar protection. That means that the current will want to flow around the outside of the equivalent circuit because the outside circuit has a lower impedance path during external faults. 3.4.

Ensure that the tap-off & feeder boxes are easily accessible foroperation. Results to be recorded on the bus duct record sheet. REB611 is a dedicated busbar protection relay designed for phase-segregated short-circuit protection, control, and supervision of single busbars. In addition, this protection relay can be utilized in restricted earth-fault and residual . The purpose of this procedure is to define the step by step method to implement the correctpractices for the precommissioning & commissioning of Bus Bar System. A stability test should be done on the busbar relay same as the general differential relay. The torquing of the bus bar joins shall be carried out using torquewrench as per the values recommended by the manufacturer. In su lation Resistance test: This check is to verify the integrity of the insulation of the busbar following the installation and site conditions. For example, a HiPot test verifies that the multiple conductive layers within a laminated bus bar are sufficiently insulated from one another at a specified voltage. 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. Three of the most important tests performed on the busbar are the High Potential or Hipot Test, Partial Discharge Test, and the Insulation resistance test, also known as a Megger Test.
