General specification for electrically suspended gyro monitor
State system for ensuring the uniformity of measurements. Quality factors of electric power measuring instruments. Methods of verification
This specification establishes requirements for the design and testing of high voltage detectors, used in the electrical power industry, to determine the presence or absence of nominal operating voltage or the measured voltage.1.1 This specification covers portable, live-line tool-supported, direct-contact type capacitive voltage detectors to be used on electrical systems both indoors and outdoors for ac voltages from 600 V to 800 kV with frequency of 60 Hz. The function of the voltage detector is limited to the detection of the presence or absence of nominal operating voltage. 1.1.1 Two types of voltage detectors are provided and are designated as Type I, audible/visual and Type II, numeric, with or without audible. 1.1.2 Two styles of voltage detectors, differing in wet conditions characteristics, are provided and are designated as Style A, indoor use and Style B indoor/outdoor use. 1.2 The use and maintenance of these high voltage detectors and any necessary insulated tool handles are beyond the scope of this specification. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 18212;Except where specified, all voltage defined in this specification refer to phase-to-phase voltage in a three-phase system. Voltage detectors covered by this specification may be used in other than three-phase systems, but the applicable phase-to-phase or phase-to-ground (earth) voltages shall be used to determine the operating voltage.
