Lodestar PT2


Cable fault indicator Lodestar PT2 is intended for detection of fault localization in overhead and cable power distribution lines of 6-35 kV.

The cable fault locator can operate in networks with insulated, grounded and resistance-grounded neutral types.

The fault detector is installed on control panel board of switchgear cell / wall-mounted.

Cable fault locator Lodestar PT2 benefits:

  • Phase-to-Ground faults detection;
  • Fault indication by switching on ultra-bright LED and mechanical flag;
  • Power supply of the indicator from DC or AC source with voltage of =220V, =110V, or mains supply ~220V;
  • Standby Lithium battery for backup supply of LEDs emergency indication while loss of main power;
  • Changing setpoints via DIP-switch/remotely;
  • Low battery level indication.

Current sensor of Lodestar PT2 is installed on the cable's armor of three phases. Indicator is installed on the control panel in the switchgear and control gear cell.
