BRISTOL, PA — TESCO Metering has expanded its portable meter testing platform with a new three-phase voltage synthesizer aimed at electric utilities upgrading grid infrastructure, broadening the company’s product lineup as utilities increase investment in advanced metering, distributed energy resources and electric vehicle charging systems.
The company introduced the Model 6440 Three-Phase Voltage Synthesizer to complement its existing TESCO 6330 Meter Site Analyzer, allowing utilities to configure portable testing equipment for commissioning, validating and troubleshooting revenue metering installations without relying on larger integrated testing systems.
The product reflects growing demand for field equipment capable of supporting increasingly complex distribution networks as utilities deploy advanced metering infrastructure (AMI), renewable energy resources and electric vehicle charging infrastructure.
TESCO said the modular platform separates voltage generation from measurement and analysis, enabling technicians to carry only the equipment required for a particular assignment while expanding testing capabilities over time.
The Model 6440 generates programmable three-phase voltage from 69 to 480 VAC, supports both 50 Hz and 60 Hz systems, delivers up to 100 VA per phase and is rated for ±0.5% voltage-setting accuracy with less than 3% total harmonic distortion. It operates from a standard 120 VAC power source and supports common utility service configurations, including WYE and DELTA installations.
The platform is intended for revenue meter commissioning, installation verification, meter accuracy testing, AMI validation, distributed energy resource interconnection testing, power quality investigations, preventive maintenance and utility workforce training.
“Utilities continue to invest in smarter grids, advanced metering technologies, and increasingly complex electrical infrastructure,” President and Chief Executive Officer Tom Lawton said. “Together, they provide utilities with a scalable platform for commissioning, validating, and maintaining today’s sophisticated revenue metering systems while giving customers the flexibility to expand their testing capabilities as their needs evolve.”
The company stated the platform supports both electromechanical and solid-state revenue meters, allowing utilities to standardize field testing procedures across legacy and newer metering systems.
