Lodestar CL0.5

Description

Description

Lodestar CL0.5 is designed to work in networks with isolated and compensated neutral with extremely low level of residual currents. This requires indicators to have unique data analysis algorithms. Real time sensors communication gives wide abilities of data analysis.

Lodestar CL0.5 benefits:

• High sensitivity — shows faults from 0.5 A
• Detecting direction — a directional earth fault detection is only useful method of a fault location in networks with low PtG currents
• Auto adjustable PtG detection - no need to tune residual current threshold
• All the benefits of CL2
