Where isolators are placed in substation?
An isolator is a non load-breaking switch, and is provides a visible means of isolating a component, such as a circuit breaker, transformer, etc., from the high-voltage lines, whenever it is necessary to perform maintenance of that component. Normally, isolators come in pairs, with one on each side of the component to be isolated. Isolators are only opened afterthe load current has been broken using a circuit breaker, and must be closed before the circuit breaker is reclosed.To work on, say, a h.v. circuit breaker, the breaker must be tripped, the isolators on either side must be opened and locked off, temporary earths attached to either side of the circuit breake- to-work card, detailing the maintenance work, must be issued to the crew by the supervising engineer.
How do you position the test instruments into the circuit ensuring the correct polarity and without damaging the circuit components?
That's a short question with a long answer. For example, when observing waveforms in a printed circuit card with a 'scope, I like to use a 10X probe with a sharp needle tip. The 10X probe presents about 10 megohms to the circuit under test, so that it doesn't load it, and the sharp needle tip penetrates conformal coatings. For example, when measuring voltages, use a 'scope set to DC coupling if accuracy is not critical. If accuracy is critical, I use a FET meter or a differential voltmeter, with a sharp needle probe. When using a spectrum analyzer, various probe schemes can be used. One of my favorites is a sniffer probe consisting of six turns of #30 wire wound round a 50 ohm quarter watt resistor, on the end of a piece of thin 50 ohm co-ax. For injecting a signal into a receiver, apply the signal across one of the input decoupling capacitors. The capacitor has enough impedance to allow the signal to be seen. Each case is different, and it up to the technician to know enough about the situation to create a strategy.
What are the basic blocks of generalized instrumentation system?
basically an input is given to the transducer, which is the 1st basic block of instrumentation system. this transducer's o/p goes to the signal conditioning circuit whose o/p is then given to the recorder, analog meter, digital transistor, printer, controller, oscilloscope and the punch card.
What card translates binary data into images on a computer screen?
If there is a dedicated card, it's commonly called a graphics card. Some computers have a graphics chip set on the motherboard, this is called integrated graphics. These are usually inferior to a dedicated card, but much cheaper.
