Figure. 5.3.18 - 151. IED equipped with arc protection.
The arc protection card has four (4) sensor channels, and up to three (3) arc point sensors can be
connected to each channel. The sensor channels support Arcteq AQ-01 (light sensing) and
AQ-02 (pressure and light sensing) units. Optionally, the protection function can also be applied with a
phase current or a residual current condition: the function trips only if the light and overcurrent
conditions are met.
The outputs of the function are the following:
• Light In
• Pressure In
• Arc binary input signal status
• Zone trip
• Zone blocked
• Sensor fault signals.
The arc protection function uses a total of eight (8) separate setting groups which can be selected from
one common source.
