CBS ArcSafe, a manufacturer of remote racking and switching solutions for low-voltage and medium-voltage switchgear, has released its PD Alert partial discharge sensor option to its Remote Racking System (RRS) line.
CBS ArcSafe’s optional PD Alert provides an additional layer of safety for technicians tasked with racking or removing circuit breakers and motor control centers. In the event of a breakdown in line-to-line or line-to-ground insulation, the PD Alert radio frequency (RF) non-contact sensor issues a visual strobe alarm or digital alarm through email or SMS text message. The PD Alert can be used with any of CBS ArcSafe’s remote racking systems, including the RRS-1 for rotary, jackscrew-type breakers; the lightweight RRS-1LT made from aluminum extrusion; the programmable dual-mode RRS-4; and the RRS-2 and RRS-2BE for remotely racking extractor-type circuit breakers or motor controls, respectively. PD Alert can also be used as a standalone partial discharge sensor for monitoring critical electrical distribution equipment.
Advanced signal processing and field configurable setup allows the operator to set do-not-exceed thresholds for partial discharge values or to issue an alert if partial discharge values indicate a condition that could be dangerous to technicians.
