Electrical window for safe compliance

Fourth Quarter 2019 Other technologies

Fluke’s new PQ400 electrical measurement window, with a permanently installed interface, gives technicians safe and 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 and allows users to make three-phase 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 analyser. Then, connect the leads for the current sensors and start making critical measurements. Once complete, the voltage and current connections are simply removed from the front panel interface and the window lid locked, leaving the internal connections in place for future use.

The Fluke PQ400 electrical measurement window enables the connection of three-phase measurement equipment to energised panels, without the need to open the panel door or wear personal protective equipment (PPE). It can:

• Reduce the risk of arc-flash and electrocution, while increasing the safety for personnel.

• Decrease maintenance costs and reduce downtime by making critical power quality and energy measurements without opening the panel door, enabling logging and monitoring at any time without disrupting operations.

• Reduce work permit requirements and processes by reducing the hazards associated with taking measurements on open panels.

• Increase measurement efficiency and reduce the need for arc-flash PPE, saving time, increasing efficiency and increasing operator comfort.
