Lodestar CL HVDD
Fault indicators for high-voltage lines
Lodestar CL HVDD detects a faulty event on overhead lines and determines the direction of emergency currents, which shows the maintenance team where the faulty section is located. It is very convenient for use on the border of different energy systems, state borders and before natural barriers (water etc.). It transfers all line parameters via GSM communication directly to the SCADA system, and sends event notifications via SMS and email to the maintenance team’s smartphones. This will help you quickly find the place of damage in hard-to-reach areas.
Lodestar CL HVDD benefits:
• All Lodestar HV indicators are equipped with a short-range radio channel of the Bluetooth Low Energy standard, which allows you to easily configure and adjust the settings from any smartphone with the Lodestar App software installed;
• It is possible to determine the status of the high-voltage line both visually, thanks to the LED indication, and using a portable remote control. (Smartphone with Lodestar App);
• CL HVDD could be easily configured from SCADA system KOMORSAN using communication unit (Smartbox, Lightbox).
