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 PPI-3 software installed


Special models of fault indicators Lodestar CL HV for High voltage lines has high designed high noise immunity. Lodestar CL HV has only with visual indication. It is convenient to locate it in a well-viewed area, for example, at the entrance of overhead lines in a substation. Lodestar CL HV 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 PPI-3 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).


Lodestar CL0.5 was designed to work in isolated and compensated networks with extremely low levels of residual current. Lodestar CL0.5 has high accuracy of all types of faults detection. The registering of faults is based on special intelligent algorithm, that makes possible to detect PtG fault and its direction from 0.5A. Real time sensors communication open up a wide range of communication sensors possibilities for data analysis. Lodestar CL0.5 benefits: • Detection of direction of all types of faults; • Different indication patterns: via ultra brigt LEDs, in SCADA system or in Lodestar App; • Extended memory. More than 200 last events can be saved in the memory and displayed in Lodestar App; • Super sensitivity. Detects all types of faults from 0.5A; • Can be used in any types grids with any types of neutral grounding; • Used in radial and double-fed lines; • Auto-adjustable PtG detection – no need to tune the residual current threshold.


Lodestar CL4 was designed for fault detection with minimum load current 4A. This is a cost-effective and reliable solution for fixing an emergency process. Lodestar CL4 supports a range of communication options, including 3G or 4G LTE communications for a high speed data transfer. Lodestar CL4 devices operate independently of each other, transmitting information about the processes in each phase. Lodestar CL4 benefits: • Minimum fault sensing 4A; • Identifies temporary and permanent faults; • Registering and storing fault information such as timestamp, event type and measured values; • Battery status control and indication.
