*****DISCONTINUED***** The Fluke PQ400 Power Quality and Electrical Measurement Window enables the connection of three phase measurement equipment to energized panels, without the need to open the panel door, or wear supplemental personal protective equipment (PPE). How It Works The Fluke PQ400 Electrical Measurement Window is a permanently installed interface that provides technicians with near instant access to electrical panels for making critical power quality and energy measurements. The PQ400 installs using a standard step drill bit and electro-hydraulic hole punch (114.3 mm, 4.5-inch hole diameter), and allows users to make threephase voltage, current and ground connects covering most measurement configurations. Once installed users can simply unlock the window cover, lift the lid, and connect the voltage leads of the logger or analyzer. Then, connect the leads for the current sensors and start making critical measurements. Once complete, simply remove the voltage and current connections from the front panel interface and lock the window lid, leaving the internal connections in place for future use.
