5.5. Arc light fiber optic loop sensor AQ-08

AQ-08 is an arc light fiber optic loop sensor. It is designed to withstand temperatures up to 125 ºC,
which makes it suitable for e.g. wind turbine windings. AQ-08 is a robust fiber optic cable with a
practically unlimited bending radius. The sensor contains hundreds of glass fiber drains that are
covered by a plastic tube, thus making it extremely strong and durable. Fiber sensors are distributed
through the protected switchgear cells.

AQ-08 sensors can be ordered in pre-manufactured lengths of 3…15 meters (3 m, 5 m, 10 m, 15 m).
It is not recommended to cut or splice the cable on-site. However, if cutting or splicing is necessary due
to the cable breaking, please contact your nearest Arcteq representative for instructions.

The fixed light intensity threshold of an AQ-08 sensor is 8,000 lux. The sensor does not require further
settings by the user. The sensor's detection radius is 360 degrees.

When requested, the ends of an AQ-08 cable can be covered with black rubber to avoid light detection
outside the protected zone (see the figure below). The covered area can be as large or small as
necessary. For more information, please consult your nearest Arcteq representative.

5.6. Sensor—unit dependencies

Different sensor types can be used with different arc flash protection units of the AQ-100 series. The
table below describes those dependencies.
