Basically there are two types of transistor: PNP and NPN.We have labelled the NPN transistor as BC547. This means you can use ANY NPN transistor, suchas 2N2222, BC108, 2N3704, BC337 and hundreds of others. Some circuits use TUN for TransistorUniversal NPN and this is the same as our reasoning[r]

Dalles, Oregon and the Sylmar Converter Station north of Los Angeles, California. Theline has two conductors with a maximum operating voltage of ±500 kV betweenthe conductors and the ground; the maximum capacity of the Intertie is 3100 MW.The large capacitance of the ac cables limits the power[r]
Large quantities of oil usually remain in oil reservoirs after conventional water floods. A significant part of this remaining oil can still be economically recovered by Water AlternatingGas (WAG) injection. WAG injection involves drainage and imbibition processes taking place sequentially, hence th[r]

Threephase transformer modeling for unbalanced distribution power flow has not been successful in phase variables. A satisfactory solution to this problem has been developed earlier, using a hybrid of phase and sequence variables. These models are not suitable for power flow methods which can provid[r]

It is important to note that except 1, all other approaches require a hybrid of phase and sequence variables. Keeping this in view, the objective in this paper is to develop new pie models for various transformer connections, which will allow the use of pure phase variable approach. Although this mo[r]
