The market’s challenge

About 80% of the faults in overhead power distribution lines are temporary and can be cleared by using reclosers.

Traditional solutions for protection and automation of overhead distribution power lines are highly complex and do not fully meet the demands from utilities, especially about single-phase networks. Most of the time, the equipment is restricted to local commands and operations, requiring the deployment of a complete crew in the field for operation and maintenance of the equipment, generating high costs and periodic interventions. Moreover, these equipments have limitations in configurations.

PROTECTION AND AUTOMATION OF SINGLE & THREE-PHASE SYSTEMS

Remote-controlled smart grid solution that reduces permanent fault events by up to 80%

Advantages Product

Protection, communication and remote control

Fully developed and manufactured by Hart BR, Rocket-1® Single-Phase Recloser combines protection, communication, automation, and remote control features in the same equipment.

Everything is useful and economically feasible, by using available IoT communication technologies.

icone-tempo-de-religamento-hartbr-02

Protection with longer reclosing times

In addition to the Sectionalizer and Switch Mode (protections off) features, Rocket-1® has 4 operations up to lockout (without the recloser dropping from the fuse cutout).
icon-app-bluetooth-iot-hartbr-02

Bluetooth and IoT Network Communication

Communication and parameterization are done locally via App (Bluetooth) or remotely via IoT networks.
icone-telecomando-via-redes-iot-hartbr

Remote Control via IoT Networks

By using the onboard communication module, it is possible to supervise and remotely control Rocket-1® via SCADA systems.
Mechanical Levers

Command system for local or remote operation

Rocket-1® Recloser is mechanically operated by the yellow and blue levers.
Local Mode
When one of the levers is pulled down, Rocket-1 goes to Local Mode, ignoring any remote commands from SCADA or App Hart Devices.
Remote Mode
When the levers are in normal position, Rocket-1 is always in Remote Mode, ready for SCADA commands and connection via App Hart Devices.
Technical Characteristics

Main technical features of Rocket-1®

Self-powered by the primary medium-voltage of electrical grid

Rocket-1® has an internal self-powering circuit and has no batteries nor electrolytic capacitors.
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

Rocket-1® has a mechanical indicator, connected to the vacuum interrupter, for “Open” and “Closed” signaling.
High intensity LEDs:
Switch Mode - Sectionalizer Mode – Three-phase Mode – Live-Line enabled - Recloser lockout - Active communication signalization (by Bluetooth and IoT)
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).
video-sensors-recloser-rocket-1-hartbr

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.
video-geopositioning-recloser-rocket-1-hartbr

Geopositioning to indicate the exact location of the fault

With an onboard GPS, Rocket-1 will dynamically inform the SCADA about the exact location of the fault. No settings are required, ensuring fast field crew deployment, in cases of permanent faults.
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.
video-telecommunication-recloser-rocket-1-hartbr

Telecommunication by IoT networks

Locally Hart Devices APP provides access to monitor and configure Rocket-1, by a secure Bluetooth connection.
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.
