[Case Study] Electric Equipment Company F

Real Trouble: The digital signage is not working! The source of the noise was identified as the lighting fixtures!

The electrical equipment company, Company F, was responsible for electrical work at a certain terminal station and was in charge of the installation of digital signage using LCD displays. The construction was progressing smoothly as scheduled, but the digital signage experienced unexplained malfunctions and system crashes. In response, our company investigated whether noise was observed during malfunctions or if there were any nearby devices generating noise. It was determined that the source of the noise was coming from nearby lighting fixtures, so we proposed the introduction of a "Noise Cut Transformer" for the power supply of the lighting fixtures. After the introduction, the malfunctions of the digital signage completely ceased, allowing it to display beautiful images.
