High frequency recommended vocabulary
IEC 60060-1 is the foundational document of the high-voltage test technique series. It establishes the vocabulary used throughout dielectric testing and lays down the requirements that any laboratory must meet when a voltage test is performed. The standard covers direct voltage, alternating voltage with power frequency, and impulse voltages of both lightning and switching type; for each it defines the waveshape parameters, the permitted tolerances on front time, time to half value and peak value, and the way these quantities are determined from a recorded waveform. It also specifies the atmospheric correction procedure that normalises test results to reference air density and humidity, so that results obtained at different altitudes and in different seasons remain comparable. Requirements for the test circuit, the reference measuring system and the calibration of dividers are given, and the treatment of disruptive discharge and flashover is defined. The document is used directly by manufacturers of transformers, switchgear, cables, arresters and insulators, and it is the reference for every subsequent part of the series.
The LVG Series complies with relevant standards, including IEC 60060-1, IEC 60060-2, IEC 61010, GB 311, GB/T 16927.1-2011, GB/T 16927.2-2011, and GB/T 116896.1-2011.
