3、-voltage prox-imity 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 600V ac at power system frequencies between 50 to 60 Hz.1.2 High-voltage proximity alarms provide audible
4、/visualalerts and may have the ability to limit movement of equip-ment.1.3 The use, installation, and maintenance of these high-voltage proximity alarms are beyond the scope of this specifi-cation. This standard does not purport to address installation, inservice care or use.1.4 This standard demons

The values stated ineach system are not necessarily
6、 exact equivalents; therefore, toensure conformance with the standard, each system shall beused independently of the other, and values from the twosystems shall not be combined.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use.
