Everything is useful and economically feasible, by using available IoT communication technologies.
Protection with longer reclosing times
Bluetooth and IoT Network Communication
Remote Control via IoT Networks
Command system for local or remote operation
Main technical features of Rocket-1®
Self-powered by the primary medium-voltage of electrical grid
The energy for its operation is stored in an ultra-capacitors power bank;
It doesn’t use batteries and electrolytic capacitors, which means reduced maintenance and hazardous waste disposal costs;
With no current passing through it, Rocket-1 has an autonomy of 14 days, being able during this period, to receive remote commands from SCADA system;
Auxiliary power supply by photovoltaic panels, located at the bottom of the equipment;
Access by Hart Devices App is always available locally, regardless the current on the primary network;
or laboratory use, Rocket-1 has a wireless charger, without the need to use a relay test bench to apply current in the recloser.
Mechanical indicator for local signaling
High intensity LEDs:
Through the App, all information is available, including a log of the last 1,000 events, with 1 ms time stamp (time stamp from onboard GPS).
Digital and analog sensors with remote supervision
Rocket-1® has internal temperature and humidity sensors, as well as an electric field sensor to detect the presence of voltage on the grid, which helps the recovery systems, giving information for a quick decision making.
Accelerometer to indicate whether the recloser is positioned in the fuse cutout or if it has been disengaged by crew, for network maintenance, for example;
Magnetic Hall-effect sensors detect the position of the manual levers;
The rated current is measured by a CT (current transformer), which ensures 1% accuracy within the entire Recloser’s operating range.
Geopositioning to indicate the exact location of the fault
Rocket-1 clock is also synchronized by the GPS signal. Thus, the event log has a time stamp with 1ms precision, allowing the sequence of events to be analyzed assertively.
Reliable time stamping also enables local access security by Hart Devices APP. Rocket-1 requests access tokens that changes accordingly to the date of the recloser.
Telecommunication by IoT networks
Rocket-1 requests access tokens, that changes accordingly to the recloser’s serial number and access date. There are three levels of access to the equipment.
Rocket-1 can be remotely controlled and configured through IoT networks. The integration with SCADA system has no limitations; all analog and digital variables are available for reading.
Technological evolution of Telecom media is guaranteed by a standardized communication bus, allowing other communication technologies, as they emerge, to be quickly integrated into Rocket-1.
