The three-phase alternating current switch gear of a converter station is similar to that of an AC substation. It will contain circuit breakers for overcurrent protection of the converter transformers, isolating switches, grounding switches, and instrument transformers for control, measurement and protection.
A switching station is a substation without transformers and operating only at a single voltage level. Switching stations are sometimes used as collector and distribution stations. Sometimes they are used for switching the current to back-up lines or for parallelizing circuits in case of failure.
A high-voltage current transformer may contain several cores, each with a secondary winding, for different purposes (such as metering circuits, control, or protection). [7] A neutral current transformer is used as earth fault protection to measure any fault current flowing through the neutral line from the wye neutral point of a transformer.
The city commission unanimously approved a nearly $600,000 contract with Geosyntec Consultants Inc. to design and permit a solid waste transfer station.
GPS' switchyard output feeds a new AEP substation located on a 1200’ x 500’ pad near the plant, Aka Guernsey 765 kV Switching Station, [19] which then connects via two 0.3-mile 765-kV transmission line sections to the east- and west-bound legs of the Kammer–Vassell line, respectively. (The Kammer substation lies SW of Wheeling, West ...
The Solid Waste Authority of Central Ohio (SWACO) was established by the Ohio General Assembly in 1989 as part of Ohio House Bill 592, which created Ohio’s current solid waste management planning and regulatory programs. [1] [2] SWACO is a government-run entity responsible for the safe and sanitary management of all solid waste within its ...
The secondary winding of the local transformer will supply the customer with either single ended single phase (N-0) or split-phase (N-0-N) power in the region's standard appliance voltages, with the 0 volt line connected to a safety earth that does not normally carry an operating current.
