isolation transformer उदाहरण वाक्य

उदाहरण वाक्य

1. Generally every AC power line transformer acts as an isolation transformer, and every step up or down has the potential to form an isolated circuit.
2. Instrument transformers may also be used as an isolation transformer so that secondary quantities may be used in phase shifting without affecting other primary connected devices.
3. If it is desired to disconnect phantom power from one channel only, this can be done by using a 1 : 1 isolation transformer or blocking capacitors.
4. Due to the transformerless design of many tube radios of this period, an isolation transformer should be used with any radio that has not had safety wiring modifications.
5. Sometimes the preamplifier is on a potential ( " off ground " ) and gets its power through a low-power isolation transformer and outputs its signal optically.
6. After some years of experience, the inventor advocated a capacitor in series with the ground of the main isolation transformer to counteract the inductive reactance of the transformers, wire and earth return path.
7. Another nit, transformers don't have to change the voltage at all, isolation transformers usually have a 1 : 1 turns ratio .-- mattb @ 2007-02-17T13 : 26Z
8. Isolation transformers are transformers for low frequency analog and digital audio connections or rarely for high-frequencies in antenna cables between TV outlets and devices ( tuner, VCR, TV, etc . ).
9. Prior to their invention, complete electrical isolation of the switch element in a chopper from the driving source for opening and closing the switch element was not possible, even through use of isolation transformers.
10. Using isolation transformers, which were bulky and expensive, in miniaturized circuits to separate the driving source and the switch element resulted in magnetic pick-up and spike feed-through due to the transformer winding capacitance.
