circuit breaker distribution transformer Vacuum Charging

Transformer oil - Wikipedia oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers.Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant.

Girl Voice Changer (online pitch changer) ― LingoJam! This is a tool to convert your voice (or an audio clip that you give it) to a girl's voice. Note that voice pitch varies a lot with age - a girl's voice will tend to be more higher-pitched compared to an adult woman due to their smaller vocal cords, so we've added a drop-down menu for you to choose how high-pitched (or "young") you want your modulated voice to sound.
