Determine the value of Isc and field current that gives the rated alternator voltage per phase. the synchronous impedance Zs will then be equal to the open circuit voltage divided by the short circuit … WebThe open circuit and short circuit test are performed for determining the parameter of the transformer like their efficiency, voltage regulation, circuit constant etc. These tests …
WebThe circuit shown in Figure 1 can effectively detect short-to-battery (STB), short-to-ground (STG), open-circuit, and short-circuit faults. The circuit uses an ADA4433-1 (U1) fully integrated video reconstruction filter as part of the video transmission signal chain and an ADA4830-1 (U2) high-speed difference amplifier as the detection circuit. Web7 de out. de 2024 · To do a short circuit test first of set the value of field current at 0 and connect the output terminals of the generator by the ammeter. After that find the value of the armature current (I A) by changing the field current. This graph among the field current and the armature current known as the short-circuit characteristic (SCC).
WebIGBT damage is the most common cause of sub-module failure , generally due to short-circuit faults or open-circuit faults . Compared to the IGBT short-circuit fault, the IGBT open-circuit faults can last for a long time without being detected, which can deteriorate the output of the MMCs and can make the capacitors in the faulty SMs over-charged [ 8 ].
