2.4 Arc alarm strategy

2.4.1 Arc mode

We divide the arcs into Instantaneous Arc and Continuous Arc.

Instantaneous Arc

The arc duration does not exceed the Instantaneous Arc Time (IAT), and there is

no arc occurring again within the Continuous Arc Time (CAT).

Continuous Arc

The arc duration exceeds the IAT, or the arc duration does not exceed the IAT,

but the arc occurs again within the CAT.

2.4.2 Arc alarm strategy

1. Instantaneous arc alarm

If the arc intensity of any channel exceeds the channel alarm threshold, an arc

alarm will be generated.

2. Continuous arc alarm

The product does not alarm when instantaneous arc is detected, but only when

continuous arc is detected.

2.4.3 Arc alarm time

The calculation method of the arc alarm times of the channel: When an arc alarm

occurs in any channel, the number of arc alarm times increases by 1. When arc faults

occur in several channels at the same time, the number of arc alarm times only

increases by 1. The product will automatically restart after 2 minutes.

However, when the arc alarm times is up to the value of the arc alarm time, the device

must be restarted manually.
