: Uses optical lens sensors to detect the intense light of an arc and current transformers to detect the accompanying current spike. Operational Principles

He grabbed a multimeter and a resistor. Following the instructions in the digitized yellow pages of the PDF, he climbed the safety cage and located the access panel on the robot's shoulder. The rain lashed against the skylight, a rhythmic drumming that matched his racing heart. abb+ufes+manual

A micro-gas generator in the PSE creates a low-impedance path to ground, causing the arc voltage to break down. : Uses optical lens sensors to detect the

: These autonomous units have a switching time of less than 1.5 ms. They are typically 210 mm high and 137 mm in diameter . Tripping Units : The rain lashed against the skylight, a rhythmic

The "brain" that receives trip signals and triggers the PSEs. It is available in two main designs:

Before energizing the high voltage:
