Can a a electric substation in a city use transformers to increase the power output?

No! A transformer changes voltage levels, not power levels. In fact, the output power of a transformer is actually a little lower than its input power, due to the efficiency of a transformer.

Why are transformer more efficient than a rotating electric machine?
Transformers inherently do not have frictional losses, but transformers and rotating machines perform completely different functions, so I'm not sure it is fair to compare them. Transformers are used to transform electric energy (the input is electric energy, and the output is electric energy). Rotating machines either take electric energy and convert it to mechanical/kinetic energy, or take kinetic energy and convert it to electric energy.
How do you measure resistance in substation?
As we all know, Transformers are majorly used in substations. Transformers are specified with their Copper loss & Iron loss impedance (similar to resistance in DC circuits) which are generally considered with AC supply. Therefore, we can calculate the total impedance byanalyzing the substation installation blue prints ORusing parameters Input voltage, currents & Output voltage current taking the whole substation as a single unit with the help of phasor diagrams. Here, you'll have to consider if the transmission is double circuited or else likewise.
Why cant you use a transformer to increase the voltage of a 60V solar panel?
The output of a solar panel is direct current. Transformers need alternating current to operate.
How do transformers reduce electrical voltage?
This type of transformer is called a Step-Down transformer. All transformers have an input to output ratio. The transformers that increase voltage are called Step-up, and the transformers that protect against surges are called unity gain. The Unity gain transformer has a 1:1 ratio and provide a mechanical way to isolate a source of voltage from a load.
Can transformers be connected in series?
A: Absolutely but the output for a power transformer will be less. the phases can also be out of phase on the output yielding no output at all.

Where can you find winding data for the Western Electric 519A audio output transformer that was used on the 142A amplifier?
You might want to try Lilienthal Transformers, DK.

What instruments are used to create electric energy from solar?
Not really instruments. Photovoltaic-cell arrays and appropriate batteries & electronic control-gear, with inverters and transformers is the output is to be a.c.

. Which type of full-wave rectifier has the greater output voltage for the same input voltage and transformers turn ratio?
well when you see on basis of output voltage the centre tapped transformers is .
What are some important types of transformers?
There are Several types of transformers are there in that some are listed below. Instrument Transformers Step Up and Step Down Transformers Single Phase Transformers Power Transformers Distribution Transformers etc. For more visit transcon industries.
Components used to build the substation?
Substation main components include the following:1. The power transformer which is the heart of the Substation. It is the Power transformer that steps up (in the case of a step up Substation for transmission) or steps down (in the case of step down Substation for distribution) the voltage e.g. 132/33kV (step down), 33/132kV (step up).2. The Auxiliary transformer (which is fed from the output of the Power Transformer). This transformer powers the substation accessories and auxiliary equipments such as controls, lighting, Substation control room etc)3. Disconnecting switch or Isolators4. Earthing switch for grounding the main line in case there is need for maintenance work5. Control relays and Protective relays for short circuit, over voltages etc6. Instrument transformers e.g. voltage transformers, current transformers that will take current from the main high voltage line in case of an over current on the line and produce a current that the protective relays can operate with.7. Supervisory Control and Data Acquisition (SCADA) systems for line monitoring and control8. DC power supply system in the form of batteries for supplying DC loads such as emergency lightings, relays, rectifiers, chargers etc.9. Lightning arrestors10. Surge arrestors11. Switchgears for the high and low voltage levels, AC/DC panels12. Circuit breakers for the high and low voltage levels
What are two ways of making a stronger voltage using Faraday's law?
Using transformers. The concept of transformers is that it can regulate voltage. Like it can increase the supplied voltage by 10 times or even more. It works in the ratio of coils. This ratio of coils are equal to the ratio of input/output voltages.
What is an injection substation?
An injection substation is a substation where a higher voltage is stepped down to a lower voltage,especially for transmission in a densely populated area.The transformer involved is often in the MVA range,so that the output can serve a wide area,or large consumers. In Nigeria,the common injection stations are: 15MVA or 7.5MVA 33/11kv injection substations.
