Instrument Transformers: What is it? (and their Advantages ...· Current Transformer (C.T.) Potential Transformer (P.T.) Current Transformer (C.T.) Current transformer is used to step down the current of power system to a lower level to make it feasible to be measured by small rating Ammeter (i.e. 5A ammeter). A typical connection diagram of a current transformer is shown in figure below.
What is an HVDC (High Voltage Direct Current) Transmission ...2019-1-28 · The HVDC converter transformer can be built as three-phase units or as single-phase units depending on voltage and power rating. When built as three-phase transformers there is generally one unit with the valve winding arranged for star connection and the other unit for delta connection.
DESIGN GUIDELINE 5.7 UNIT SUB-STATION ROOMS· PDF fileProvide a backwater check valve for the floor drain. The backwater check valve shall be located outside of the room. When a floor drain is provided, provide a water leak detector adjacent to the floor drain and tight to the wall so it isn't a trip hazard. The leak detector shall be outside of the working space of the substation.
