A personal electrical injury protection system is provided which can be worn by electricians, construction workers, or other individuals working around or with low-voltage lines (i.e. generally less than about 600 volts). The personal electrical injury protection system has both a proximity warning component which provides a warning of potential electrical hazards upon close approach to the low-voltage power line and an electrical contact protection component which turns off the power upon actual electrical contact with the power line. The present personal electrical protection system relies on a radio frequency transmitter attached to the worker or person to be protected and a radio receiver/controller connected to the power line. The radio frequency transmitter has a low frequency generator which is used for electrical-contact protection and a high frequency generator which is used for proximity warning.
