Power Semiconductor Devices - Thyristor and Triac· Thyristor 2.5A; Peak Repetitive Off-State Voltage, Vdrm: 600V; Current Igt: 500µA. The thyristor, also called a silicon-controlled rectifier (SCR), is basically a four-layer three-junction pnpn device. It has three terminals: anode, cathode, and gate. The device is turned on by applying a short pulse across the gate and cathode.

A legacy of transformation | T&D World rigidity of the transformer will become one of the most vital performance factors for the future. There are three reasons for this: The ability to withstand short-circuit (SC) stresses; Seismic requirements; Transport handling; SC forces give rise to mechanical forces on windings that can reach hundreds of tons in milliseconds.
Dry-type transformers - Hitachi ABB Power Grids ABB Power Grids offers a full range of dry-type transformers with primary voltages through 72.5 kV built according to all major standards including IEC and ANSI. To minimize environmental contamination and fire hazard, customers are specifying dry-type transformers more frequently.
Power transformers have delivered more than 20,000 power transformers (over 2,600 GVA), including over twenty 800 kV UHVDC and over five hundred 735 - 765 kV AC units, to all major global markets. Our entire range is the result of our own research, development and manufacturing, which makes us unique in the industry.

Station Transformer - an overview | ScienceDirect Topics transmission infrastructure typically consists of (Fig. 16.2): (a) an offshore transformer platform that collects the power from the wind farm and increases the voltage; (b) a sea cable that transports the power ashore; and (c) a transformer station onshore. For HVDC connections, the transformer stations also accommodate the AC/DC converter.
