The support system for the bus bars is complete. About. A stability test should be done on the busbar relay same as the general differential relay. 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. Check earth leakage circuit breakers by means of RCCB tester, selecting 50% 100%, 150% of the rated sensitivity currents and the respective trip time to be recorded. All covers shall be properly replaced upon completion of torquingof each joint. <>>> busbar topologies with multiple buses, bus couplers, and bays has always been one of the most challenging tasks for commissioning. REB611 is a dedicated busbar protection relay designed for phase-segregated short-circuit protection, control, and supervision of single busbars. This test is especially important for medium voltage, multilayer laminated bus bars, inverters, and any critical power conductor applications where electrical insulation is of paramount importance. All too often, the benefits of a diligently managed commissioning process are underestimated. After attaining approval, test/report sheets to be signed off from all mentioned in the signature block. Education: 3 0 obj Test/report sheets to be distributed as per Project Specifications. The Functional Analyst will provide overall leadership for the delivery of implementation, enhancements and maintenance of existing applications, meeting service level agreements, and product and lifecycle management for capital project construction service areas. All busbar installed with correct phase sequence and Tap off location as per approved drawing. The objective of testing is to provide confidence in the real-world performance of a part design.

After completing the procedures mentioned in section 6.0. Ensure all joint covers are firmly secured. Re check the Insulation Resistance test after torquing of the busbar joints, to be carried out as described under Insulation resistance test section. 1.2. jumper cables, terminals and various devices by using an infrared scanner. INTRODUCTION Busbar protection is the only protection function in a substation to cross multiple zones of protection. The action you just performed triggered the security solution. Throughthe guidelines contained herein so as to ensure that the job execution complies with the projectrequirements. Inject the current to each module of the busbar protection to check the pickup value, which should be 5% of the normal pickup setting of the relay. 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. Desired Profile - Protection & SAS Testing & Commissioning Engineers - Graduates having degree / diploma in Electrical engineering having 1 7 years experience of onsite testing & commissioning of protection relays and SAS schemes .
