1.1 UNDERSTANDING E-FIELD DETECTION
The Sigalarm system is a reliable and finely tuned “radio” designed to receive only
one selective source: the detectible E-field present around all AC high voltage
power lines. The strength of the signal (E-field) depends on the lines voltage and
the distance from the lines. Simple adjustment of the settings on the Sigalarm
unit will provide accurate and repeatable warnings. After the desired setting is
made, a visual and audible alarm will occur whenever the set point/E-field reading
is detected.
1.2 SAFETY REGULATIONS
It is the equipment operator’s responsibility to know and follow all OSHA, employer,
utility, and equipment manufacturers’ instructions, rules, and regulations.
1.3 SAFETY WARNINGS
Overhead power lines are a constant danger to anyone working with or near
equipment that can come into contact with these high voltage lines. No warning
system should be used in place of standard safety rules and precautions. No
warning device can absolutely prevent an accident. When properly installed and
operated Sigalarm products will provide reliable and repeatable WARNINGS of the
presence of voltage.
