A special type transformer is a custom-engineered electrical device built for unique industrial, testing, or measurement tasks that standard power and distribution units cannot handle. They manage specific demands like heavy current, high frequency, exact metering, or severe operating conditions.
Common Types of Special Transformers
Instrument Transformers: Includes Potential Transformers (PT) and Current Transformers (CT) that step down high voltage or heavy current to safe, measurable levels for meters and relays.
Rectifier Transformers: Converts alternating current (AC) to direct current (DC) for heavy industrial processes like electroplating and metal refining.
Furnace Transformers: Delivers high-current, low-voltage power required to melt scrap metal in electric arc or induction furnaces.
Isolation Transformers: Decouples electrical paths to block faults, reduce noise, and protect sensitive medical or electronic gear.
Testing Transformers: Produces very high voltages for insulation and breakdown testing on heavy switchgear and cables.
