The most common way of dropping AC voltages is with a transformer. 80 volts is not a common secondary voltage. This type of transformer would be manufactured for OEM (Original Equipment Manufacturer) only equipment and not for the general public. A motor shop might be able to wind one for you if you have a transformer core that they could use. You would have to let the winding shop know what the connected load current is at 80 volts.
There are no adptors to plug a 240v plug into a 120v receptacle. 240v requires two hot wores and a neutral and ground. 120v requires one hot wire, a neutral and a ground. If you have something that runs on 240/120 you need the cord and adaptor that came with the equipment as you willl need the wires to mate up accordingly.
three phase full load 1000/(1.732*220)*24 = 62.98amps
You would need to have a 12 v ac supply available to step it up to 230 v with a transformer. Please explain what kind of power supply you are working with so that an answer can be provided.
I think it depends on country to country. In India, it is 220V-230V
Yes, you can use a 220-volt circuit in the basement to run branch circuits for 110-volt lighting. You would need to install a step-down transformer near the lighting circuits to reduce the voltage from 220 to 110 volts. Make sure to adhere to electrical codes and regulations when setting up the system to ensure safety and proper functioning.
By using a Variac Transformer
You use varistor wich has the max voltage for that aplication example:vacuumcleanermax allowed voltage is 240v ac so you chose aprox. 250 V varistor.
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
240v ac
Yes, the AC current can be amplified by using Step-down transformers, but one problem is the AC voltage will decrease with Step-down transformer.
Use a step down transformer 240 primary to 120 secondary. You must know what the connected load (amps) is so that you don't overload the transformer. Small transformers are rated in VA.
220v 50Hz
A transformer steps the voltage of an electrical power supply up or down. The transformer must be correctly designed for the voltage and current levels that it is intended for. Only ac can be used with a transformer, which is designed to work at a particular frequency.
Because transformers are usually used to step down AC votage, however they usually can accept DC power to step down or up.

Yes
The recommended AC breaker size for a 240V air conditioning unit is typically 20 amps.
