A solid-state transformer (SST) is an AC-AC converter, sometimes called a power electronics transformer (PET), that replaces ...

Potential Transformer (PT), also known as a voltage transformer (VT), is used to step down an AC voltage to a safe level for use in metering and protective relays. It is a type of instrument ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

With any switchboard or switchgear lineup, you can order ammeters, voltmeters, frequency meters, etc. These meters come with factory-installed instrument transformers, which are needed to convert the ...
