HVDC: When and How It Is Used in TransmissionAlternating current ultimately won since a transformer could be used to increase or decrease voltages, and no similar option existed at the time for direct current. Advantages and Disadvantages of HVDC. Alternating current travels as a wave, and is constantly changing direction (60 times per second, defined as 60 hertz, in North America).

GIS vs AIS - Substation Earthing· The results confirmed a high percentage of current circulating through the enclosure (in the range from 50 to 85% of the 2000 A of the primary current). It was also found that a high level of circulating current (up to a 50%) was present in the inter-phase copper earth straps which shunt the individual phase enclosures.

Bushings - The Ardry Group ABB Power Grids Distribution Transformer Components offer both high voltage and low voltage bushings designed for use in pad or surface mounted transformers. The bushings insulate the current carrying conductor from the tank, allowing for termination of both the airside conductor and the transformer leads.

Green Gas for Grid - g3 - SF6 Free Solutions 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

Electrical test equipment | power station to plug | Megger Mount - UK power manager. An essential stage in the commissioning of any power cable is testing prior to energisation. Properly performed, this test will provide the information needed to ensure that any problems that have occurred during the manufacture or installation can be corrected before they lead to costly and disruptive faults.

Current Transformer (CT) - Construction and Working Principle· Dead Tank Current Transformer. The figure depicts dead tank CT (two-bushing) which is very compact in size and can be mounted on a steel structure near the outdoor circuit breakers.. A CT having more than one core and more than one secondary winding is known as a multi-core CT (for example, a CT having metering and protection cores).
