The Fluke 1773 is a three-phase power quality analyzer built for fast troubleshooting of electrical distribution systems. It automatically measures the core power and power-quality parameters technicians need, then presents an at-a-glance view of system health so problems can be spotted and diagnosed quickly. In a single instrument it logs voltage, current, and frequency along with power, dips, swells, and harmonics, and it captures high-speed transients up to 8 kV to catch the fast disturbances that disrupt sensitive equipment.
As the entry point of Fluke's 177x analyzer line, the 1773 powers directly from the measurement circuit, so there is no line cord to manage during setup or extended logging sessions. It is offered in a standard configuration and a Basic kit, giving facilities, plant maintenance, and field service teams a self-contained tool for energy and power-quality studies, intermittent-fault hunting, and routine system verification.
