WebDec 23, 2024 · The resistor in parallel with the photodiode is called the shunt resistance (R SH). As with current sources in general, ideal operation is achieved when R SH is infinite. With infinite (or, in real life, extremely high) shunt resistance, a current source delivers all of its current to the load, and the current-to-voltage ratio is determined entirely by the load … WebShunt reactors are two types like dry-type & oil-immersed. Power transformers are available in different types like autotransformer, polyphase, leakage & resonant. Shunt reactor has a large amount of magnetizing current. As compared to a shunt reactor, it has a less magnetizing current. Shunt reactor is rated in MVAr.
