PRODUCT OVERVIEW

The arc light protection system protects the operators from injury and reduces the property damage when an arc fault occurs in a switchgear cabinet. When it occurs, the arc light explodes at 300m/s, destroying anything in its path. As long as there is an uninterrupted power in the system, the arc light will always exist in the system. To minimize the hazards of arclight, we need a safe, fast and effective arc light protection system.

KLD-AP series arc protection system can quickly detect arc faults and trip the circuit breakers. In order to ensure the reliability of the system, the arc protection system needs to meet two criterions to take actions: arc light and overcurrent. The system will send a trip command signal when it detects both arc light and current increments; and the system will send an alarm signal, not a trip command signal when it only detects arc light or current increments.

Double criterion ensures the reliability of the action taken by the whole set of equippment, and the output trip signal is fast （＜1ms）that can cross all other protection and delay, which is of great significance. The response time is calculated in milliseconds.
