(Specification)Standard Specification for High Voltage Detectors—Part 1 Capacitive Type to be Used for Voltages Exceeding 600 Volts AC
Standard Specification for High Voltage Detectors—Part 1 Capacitive Type to be Used for Voltages Exceeding 600 Volts AC
ABSTRACT
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. 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. The following tests shall be performed: voltage; low temperature impact; drop/impact; humidity; wet test; battery life test; durability of labeling; vibration resistance; continuous operation rating; response time; testing the self-test function; acceptable audible indication; acceptable visual indication; visual inspection; method to measure threshold voltage; interference voltage testing; leakage current testing; dielectric testing for detector housing; and wet testing.
SIGNIFICANCE AND USE
4.1 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.
SCOPE
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 50/60 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: 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.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
