Abstract :
A short-circuited disorder is one type of interference that can damage components of the electrical power system. A short circuit analysis is required to determine the value of short circuit currents which flowing on the system. The current can be used to find the capacity of CB that can be installed to secure the system. To deal with the addition in Jakarta and surroundings areas has been carried out the construction of the Gas Insulated Switchgear Extra High Voltage 500 kV Duri Kosambi consisting of two units of Intesrbus Transformers where each of IBT has a capacity of 500 MVA and consists of the bay 500 kV towards the Muara Karang Baru. At the Duri Kosambi 150 kV substation there is bay IBT that has been connected with bay of Muara Karang Baru and effected in the loss of bay Muara Karang Lama on the lin of Duri Kosambi 150 kV substation, therefore it is necessary a review of the capacity of the CB on each conductor in the Duri Kosambi 150 kV substation. In this thesis, will be discussed the calculation of the largest short cicruit currents (transient) single phase and three phase using software Power Factory to determine the capacity of circuit breaker in the bay Daan Mogot Duri Kosambi 150 kV substation. The value of the largest short circuit current in bay Daan Mogot Duri Kosambi 150 kV substation is 16,674 kA and requires a power breaking capacity of 4332,0322 MVA.
