Get PriceQuantitative Optical Gas Imaging System for GF620/GFx320/GF320. The QL320 is a quantitative optical gas imaging (QOGI) system that allows surveyors to measure the leak rates for methane and other hydrocarbons. This eliminates the need for secondary sampling with a toxic vapor analyzer or similar tool.

Direct measurement of high voltages is possible up to about 200 kV, and several forms of voltmeters have been devised which can be connected directly across the test circuit.
Get Price2020-9-26For voltages above 123 kV and for high values of rated power (usually above 100 MVA), for handling and econo mic reasons it is usual to use single phase transformers.
