This endeavour falls in line with TNB’s challenge to stay relevant and up to date with the modern consumer needs by shifting towards online monitoring, remote supervision and switch control. This video is unavailable. In term of substation land size, land price and building price, there is a vast cost saving for developers to install a compact 500 kVA substation in comparison to the conventional single chamber 500 kVA. Read about company. This material does allow the flow of electrons within it. Your Premier Secondary The wave is tripping high-frequency waves and is diverting the waves into telecom panel. The isolator in the substation is a mechanical switch that is deployed for isolation of circuits when there’s an interruption of current. VCB is also called vacuum insulated switchgear. Compact Substation Components and Their Functions. Capacitor banks are determined as a collection of several identical capacitors. The utility is also taking into consideration the network security and restoration time to customers. EWT Pre-Fabricated Substation unit is one of the most economic, convenient, effective equipments and friendly solutions – easy and safe to operate substations. The new policy of compact substation of 500 kVA capacity is encouraged to be installed for new housing development (domestic customers) only. For detailed information, you may contact Ms Tan Siew Hwa at E-mail: tshwa@tnb.com.my. Separable plug-in type connector at transformer HV side and RMU connections for fast installation. RATING. In TNB, types of VCB used are TAMCO, EPE and AICHI. The circuit breaker has two mobile contacts that are off condition in normal cases. It is pre-fabricated secondary sub station containing, distribution transformer, medium voltage switch gear, low voltage switch board, connections and associated equipments in a compact unit. Embed. 30 V dc supply from battery bank is used to operate the relay system of VCB. equipment located in populated areas. They offer high voltages and are much affordable in cost. Share.
