Floco® is a smart grid solution for locating transient and permanent faults in medium-voltage overhead distribution lines.

The Challenge of Distribution Automation

Low level of monitoring for electrical distribution network makes fault detection and restoration time more time slow and extensive.

In most cases of power outages, utility is informed through a contact from the consumer to the call center, but many times, the problem reported is not a failure in the power grid, but in the residence’s installation.
The absence of real time information makes the detection and correction time of the fault, longer and more extensive, because the crew needs to inspect long sections of the grid, checking point by point (transformer burnouts, broken links, problems with switches, poles falling, broken cables, tree branches touching the cables, etc.).

Transient Fault Detection

Algorithms for fault identification

The temporary fault detection logic checks for abrupt current variation and consequently, return to normal conditions, providing a predictive action of field crew (before the fuse link burns out).
The overcurrent detection will follow the configuration of Floco, i.e., automatically, di/dt, or pick-up setting. In case of a temporary fault detection, Floco will flag the event by flashing its LEDs in yellow.
The permanent fault implies the absence of voltage and current for a predetermined time (determined by the “Recloser Coordination Time” setting parameter), and the dropping of the fusetube, i.e. Floco flags the faults in different ways.
In a permanent fault, Floco checks the overcurrent event according to its configuration, and then, the fusetube drop. In a permanent fault, Floco flags the event by flashing its LEDs in red.
Automatic Detection
Floco leaves the factory in automatic mode, being not necessary any configuration to startup. The automatic overcurrent detection algorithm detects an abnormal condition in the variation of the phase and the amplitude of the current, generating a fault event.
di/dt Detection
Optionally, Floco can be configured to operate by the current differential as a function of time. The di/dt mode considers the current differential in absolute values, within a predetermined space of time, to indicate a fault.
PIOC Mode
Floco can also be configured to operate by the instantaneous overcurrent function (ANSI 50), where the current pick-up and the detection time (delay) are set in absolute values.
Technical Characteristics

Main technical features of Floco®

sensor-floco-indicador-de-faltas-hartbr-brasil

Self-powered by the primary current of distribution line

Floco® has an internal self-powering circuit and has no batteries, nor electrolytic capacitors.
The energy is stored in an ultracapacitors power bank;
No batteries are used, so it’s not required periodic maintenance and consequently, batteries disposal, eliminating operational costs;;
It sends fault information to the remote supervisory system, even after the fusetube has been dropped out;
Over than 6 hours of autonomy, with LEDs signaling locally the fault;
Access via App Hart Devices is always available locally when the primary current is over than 1A;
Floco has an USB-C power supply connector for laboratory uses.

Digital and analog sensors with remote supervision

Floco® has internal temperature and humidity sensors;
Accelerometer to indicate whether the fusetube is positioned on the cutout or if it is dropped out, due a fault;
Primary current is measured by a CT, with a nanocrystalline core, ensuring accuracy better than 1% within the entire operating range of Floco®.
In addition, Floco® has an electric-field sensor to detect the medium voltage presence, which helps the recovery systems of utility.

Manual phase selector

Electrician selects the correct phase where Floco will be installed;
A hall-effect sensor detects the installation phase, Phase A, B, or C;
In the event of a fault, Floco will report the correct phase to the supervisory system;
No special tools or software configuration is required.
