Method for Compensating for Ambient Light for an Arc Flash Detection System for an Electrical Equipment and Arc Flash Detection System for an Electrical Equipment

An arc flash detection system for an electrical equipment, the arc flash detection system comprising a data processing apparatus comprising a processor adapted to carry out a method for compensating for ambient light for an arc flash detection system for an electrical equipment, the arc flash detection system including a first optical sensor for detecting an arc flash, the method comprising:

• initiating a recording mode in which a first output signal of the first optical sensor is recorded, wherein recording the first output signal comprises storing a first plurality of values, wherein each value of the first plurality of values is representative of a level of ambient light condition in or around the electrical equipment;
• terminating the recording mode after a recording time period;
• determining, based on the first plurality of values, a first quantity characterizing ambient light in or around the electrical equipment;
• and
• configuring the arc flash detection system to compensate for ambient light based on the first quantity.

A computer program comprising instructions which, when the program is executed by a computer, cause the computer to carry out a method for compensating for ambient light for an arc flash detection system for an electrical equipment, the arc flash detection system including a first optical sensor for detecting an arc flash, the program comprising:

• instructions for initiating a recording mode in which a first output signal of the first optical sensor is recorded, wherein recording the first output signal comprises instructions for storing a first plurality of values, wherein each value of the first plurality of values is representative of a level of ambient light condition in or around the electrical equipment;
• instructions for terminating the recording mode after a recording time period;
• instructions for determining, based on the first plurality of values, a first quantity characterizing ambient light in or around the electrical equipment;
• and
• instructions for configuring the arc flash detection system to compensate for ambient light based on the first quantity.
