Lodestar CL25

Description

Description

Lodestar CL25 - a simple solution in terms of the power system reliability enhancement. Lodestar Cl25 is a conductor mounted faulted circuit indicator (FCI), which is used in medium voltage power distribution networks. Lodestar CL25 is developed to detect a short circuit and earth faults occurring in power distribution networks.

Lodestar CL25 benefits:

• Brightest Light 360° Visibility — 3 ultra-bright wide-angle LEDs provide overlapping fields of light.
• Identifies Temporary and Permanent Faults — The distinct temporary (single blink) and permanent (triple blink) fault indication patterns provide the flexibility of locating the cause of permanent and self-clearing faults.
• CL25 is capable of dynamically changing the sensitivity based on a load current. It can detect faults with as litle as 25 A phase current when loads are light and automatically increase its trip threshold to remain secure for up to 700 A loads.
• Auto-Detect Network Frequency — intellectual algorithms allow it to work in networks with frequency of 50 or 60Hz without reconfiguration

Optimal factory settings allow to use Lodestar without any configuration in most cases. Just activate the device and place it on a conductor - CL25 will do its job in the best way possible.
