Sentinel HV Aerial
The Patent Pending Sentinel HV Aerial High Voltage Protection System can be retrofitted to any machine that may have contact with aerial electrical conductors. The small mounting footprint allows installation to almost anywhere along the boom.
The system prevents the machine moving within its exclusion zone by interfacing computer controls and machine controls to monitor and override as required. The Control Interface Module monitors both machine control motions and the AC sensors.
When a powerline is detected, active machine motions become locked-out, preventing the machine from moving closer while allowing the operator to direct the machine away from the electricity source.
The Sentinel HV Aerial High Voltage Protection System uses a capacitive sensing and active filtering technology to remove unwanted interference from radio frequency and other sources, minimising nuisance detections.
It uses wireless sensors over a 900 MHz Military-Grade RF communications network from a BaseController, ensuring consistent protection of machines. As the system operates in the ISM band below the maximum power settings permitted, it does not require a permit or license to use in Australia and many other countries.
The system is designed to comply with Part 15 of the FCC rules. The Sensors and the BaseController are both programmable and the firmware is upgradable, allowing the system to be customised to an unlimited number of applications.
The sensors consistently detect distribution voltages commonly used in Australian Electricity networks: 11KV (11,000v) at 50 hertz and above. The System is tested for operation at 5Kv, to ensure a margin for most machine and install applications. It will not detect low voltage under 1,000 volts with consistency or predictability for ensuring safe working distances.
The Sentinel HV Wireless Sensors are self-sufficient, self-powered, AC Non-Contact Voltage Detectors. They feature a built-in, solar charging cell and battery pack, allowing the sensor to operate from a couple hours of sunlight per day.
