In 1956, a large property in Beaverton became available, and the company's employee retirement trust purchased the land and leased it back to the company. [10] Construction began in 1957 and on May 1, 1959, Tektronix moved into its new Beaverton headquarters campus, [10] on a 313-acre (1.27 km 2) site which came to be called the Tektronix Industrial Park.
A Tektronix 465 portable analog oscilloscope is a typical instrument of the late 1970s. In the 1960s Tektronix introduced the relatively compact 450 series of portable oscilloscopes, starting with the 50 MHz 453. The 453 was superseded by the 454. There was also a 422 15 MHz AC/DC portable made. [1]
A self-protected transformer consists of an internal fuse and surge arrester; other transformers have these components mounted separately outside the tank. [12] Pole-mounted transformers may have lugs allowing direct mounting to a pole or may be mounted on cross-arms bolted to the pole.
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $335 in 2023) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath Company.
Buck–boost transformers can be used to power low voltage circuits including control, lighting circuits, or applications that require 12, 16, 24, 32 or 48 volts, consistent with the design's secondaries. The transformer is connected as an isolating transformer and the nameplate kVA rating is the transformer’s capacity. [2]
400 MVA 220/155 kV phase-shifting transformer.. A phase angle regulating transformer, phase angle regulator (PAR, American usage), phase-shifting transformer, phase shifter (West coast American usage), or quadrature booster (quad booster, British usage), is a specialised form of transformer used to control the flow of real power on three-phase electric transmission networks.
Toroidal transformers have a lower external magnetic field compared to rectangular transformers, and can be smaller for a given power rating. However, they cost more to make, as winding requires more complex and slower equipment. They can be mounted by a bolt through the center, using washers and rubber pads or by potting in resin.
