ANALISIS ARUS TRANSIEN PADA SISI PRIMER TRANSFORMATOR TERHADAP PELEPASAN BEBAN MENGGUNAKAN SIMULASI EMTP
ABSTRACT: Transient phenomena
can be happened at electrical equipment, like primary side of transformer,
transmission circuit, generator, etc.
This condition caused by external or internal trouble of equipment, like short
circuit, switching equipment. This condition can be happened in short time and
it has big magnitude value, then it will effect to electrical equipment. If the
transformer has short circuit trouble, switching trouble, big current will flow
to transformer circuit.
This research will count the
current transient value at primary side of transformer, by using EMTP
(Electromagnetic Transient Program). Based on the simulation to 21,5 MVA
transformer, 1241 A nominal current,
this research have result that over load value more than 22,5 MVA will have
1243 A current transient. This value is more than nominal current value of
primary side, it caused by, if load have big value and primary current have big
value too.
