Hitachi - Wikipedia,_Ltd.Hitachi was founded in 1910 by electrical engineer Namihei Odaira in Ibaraki Prefecture. The company's first product was Japan's first 4-kilowatt (5 hp) induction motor, initially developed for use in copper mining. [citation needed]The company began as an in-house venture of Fusanosuke Kuhara's mining company in Hitachi, Ibaraki.Odaira moved headquarters to Tokyo in 1918.

Measuring partial discharge in GIS | Think Grid a consequence, a GIS is much more compact. In fact, gas-insulated substations can be down to one-tenth the size of their air-insulated cousins, depending on the voltage level. The use of gas insulation in the power system network has developed rapidly thanks to its compact nature, low maintenance requirement and reliable operation.

HDE Underground Cable Fault Tester – Reptame Underground Cable Fault Tester, model UCT-8, is a lightweight, one-piece operation for underground DC leakage current testing. This tool is used to test the de-energized primary shielded voltage cable for a fault. Test results are clearly displayed as an analog bar graph along with an indication of a good or faulted cable.
Global Switchgear Market, By Insulation (Air Insulated ...· Based on insulation, the market can be segmented into air insulated, gas insulated and others. The gas insulated segment is expected to hold the largest market share during the forecast period on account of its use in various industries for fulfilling the high demand for energy.
Power Transformers - Auto Transformer Manufacturer from Nashik HVDC converter stations transform the voltage from AC to DC and vice versa. The HVDC transformers operate with the applied DC electric stress in addition to the AC stress. In conventional AC transformers the high stresses are concentrated mainly in the oil, whereas in DC transformers the high stresses occur in the solid insulation system.
