Cable systems for insulating gas ring main units - EE Publishers

The ring main unit acts as a T-off point to a particular customer or transformer. Common in this application are mini substations where ring main units feed transformers, which in turn supply the low voltage network. Fig. 2 shows a typical Sulfr hexafluoride ring main unit commonly used today. NRS006 and SANS1874 are the recommended standards for ring main units.Get price

Units used in IR spectroscopy

Units used in IR spectroscopy The wavelength of light in the IR region varies from about 2.5 to 40 μ where 1 μ= 10-4 cm. Since λ cmν sec-1 = c and E = h ν, then ν= c/ λ; νis proportional to 1/ λ, the general convention in IR is to list frequencies proportional to energy. Frequencies in IR are generally expressed in 1/ λunits; ie cm-1Get price
