2. 2N3055 - Wikipedia

   en.wikipedia.org/wiki/2N3055

   The 2N3773, with a TO-3 case has slightly lower gain but significantly higher maximum ratings (150 W, 140 V ceo, 16 amps). The 2N3054 is a much lower power version of the 2N3055, rated at 25 W, 55 V and 4 A, but became almost obsolete about the late 1980s when many TO-66 devices were withdrawn from mainstream manufacturers's lists.

3. Voltage transformer - Wikipedia

   en.wikipedia.org/wiki/Voltage_transformer

   A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT. The circuit diagram for a simple capacitor voltage transformer

4. IDC (electrical connector) - Wikipedia

   en.wikipedia.org/wiki/IDC_(electrical_connector)

   Modern IDC technology developed after and was influenced by research on wire-wrap and crimp connector technology originally pioneered by Western Electric, Bell Telephone Labs, and others. [3] Although originally designed to connect only solid (single-stranded) conductors, IDC technology was eventually extended to multiple-stranded wire as well.

5. High-leg delta - Wikipedia

   en.wikipedia.org/wiki/High-leg_delta

   Center-tapped delta transformer Center-tapped delta transformer voltages. High-leg delta service is supplied in one of two ways. One is by a three-phase transformer (or three single-phase transformers), having four wires coming out of the secondary, the three phases, plus a neutral connected as a center-tap on one of the windings.

6. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   A transformer supplying a three-wire distribution system has a single-phase input (primary) winding. The output (secondary) winding has a center tap connected to a grounded neutral. As shown in Fig. 1, either end to center has half the voltage of end-to-end. Fig. 2 illustrates the phasor diagram

7. Die (integrated circuit) - Wikipedia

   en.wikipedia.org/wiki/Die_(integrated_circuit)

   A die, in the context of integrated circuits, is a small block of semiconducting material on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs ) through processes such as photolithography .
