ASTM F3283/F3283M-18

1.1 This specification covers non-contact high-voltage proximity alarms used to detect high voltage alternating current (ac) on overhead power lines. The high-voltage proximity alarm (HVPA) is limited to the detection of voltage greater than 600 V ac at power system frequencies between 50 to 60 Hz.

1.2 High-voltage proximity alarms provide audible/visual alerts and may have the ability to limit movement of equipment.

1.3 The use, installation, and maintenance of these high-voltage proximity alarms are beyond the scope of this specification. This standard does not purport to address installation, in service care or use.

1.4 This standard demonstrates the high voltage proximity alarm (HVPA's) ability to detect an e-field, and not the effects of various configurations of multiple power lines.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.6 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. Specific warnings are given in 9.1.4 and 10.9.2.

1.7 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.
