They limit the duration and the amplitude of the flow of the current. For instance, hydropower and multiple thermal plants are linked together. They limit the duration and the amplitude of the flow of the current. They offer high voltages and are much affordable in cost. FEATURE & ADVANTAGES Precast concrete CSUs are weather-resistant and suitable for harsh environment, with robust design to offer different layouts as per equipment and application requirements. This component of the compact substation is used for transfiguring high voltages to low voltages. For the new layout design of 11/0.4 kV in TNB Distribution, Ms Tan elaborated that there is an urgent need in monitoring the tapping point of current and voltage, as well as kWh meter for LV bulk customers and metering room to be part of TNB substation building. Internship Report TNB … Her presentation covered the new features in the substation layout, new LV bulk customer metering room, connection scheme, roof slab requirement, fire fighting system requirement and fencing requirement. 0% 0% found this document useful, Mark this document as useful. 433kV sub-station is available at TNB offices. Bidaut 2P. This web browser either does not support JavaScript, or scripts are being blocked. The substation is a compact enclosure consisting of MV switchgear, a transformer and an LV switchboard located in three separate compartments which are segregated from each other by means of partitions in order to ensure personnel safety. Degree of Production Busbars are utilized to bring big current and to distribute current to various circuits in equipment or switchgear. Compact Substation Components and Their Functions. We will always be behind you and good They aren’t stimulated with arc-quenching devices as well. The Compact/Package Substations are equipped with SF6 Ring Main Unit Switchgear, Distribution Transformer and LV Switchboard. 2 Load Break Switch + 1 Fuse Switch. We hope we presented you enough information about the different components of a compact substation and their corresponding functions. cooperative partner in China for your logistic business. In TNB, types of VCB used are TAMCO, EPE and AICHI. This video is unavailable. Precast concrete compact substations unit is designed to house distribution networks for utilities and for the residential, industrial and infrastructure sectors. Conventional substation designs are of indoor type (equipment housed in a permanent building) and out-door type (ground-mounted or pole-mounted). You will also find other types that are different according to their duties. ITEM being vendor to Tenaga Nasional Berhad (TNB) for 11KV VCB and 33KV GIS. 4kV sub-station is available at TNB offices, and publicly available in TNB website: Substation Design Booklet. It safeguards the equipment from other damages like: A circuit breaker is a kind of switch used for opening or closing circuits when a fault happens in the system. Of the total, only 196 have reopened and resumed operations. A substation surge is situated at the beginning of the substation as observed from incoming transmission lines. It is designed in accordance with IEC-61330 standards. You will find different kinds of insulators. This is a device used for the conversion of high-value currents into lower values. Provision for maximum safety in public area. 500kV 50 kA, 1s ii. PMU serves as main supply sourceto: i. FirstlevelofDistributionprimarynetwork(33kV,11kV) ii.
