1.1 This specification covers non-directcontact-type high-voltage proximity alarms to use on equipment operating at 10 ft (3 m) or more from an overhead high-voltage alternating current (AC) power line. The function of the high-voltage proximity alarm is limited to the detection of 50 to 60 Hz frequency above 600 V AC. 1.2 High-voltage proximity alarms provide audible/visual alerts with or without 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 specification does not purport to address installation in service care or use. 1.4 Units- The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.5 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. 1.6 The following testing demonstrates the HVPAs ability to detect an e-field and not the effects of various configurations of multiple power lines.
