New lightweight artificial resistive loads deliver precise, field-ready load simulation to improve meter testing accuracy, portability, and efficiency.
BRISTOL, PA, UNITED STATES, January 26, 2026 /EINPresswire.com/ — TESCO® Metering, a trusted provider of American-made metering equipment and custom utility products for the electric utility industry, today announced the launch of the 326P and 326X Artificial Resistive Loads. These next-generation load simulation solutions are engineered to deliver precise, portable, and field-ready resistive loads for meter testing, calibration, and diagnostic applications across utility environments.
As electric utilities continue to modernize grid infrastructure and expand advanced metering deployments, the need for accurate, repeatable, and practical load simulation tools has become increasingly critical. Field technicians and meter lab teams must validate meter performance under real-world conditions while balancing accuracy, portability, and operational efficiency. The 326P and 326X address these demands by combining precision resistive load simulation with lightweight, rugged design optimized for both field and laboratory use.
Purpose-Built Solutions for Diverse Testing Scenarios
The 326P Artificial Resistive Load is a versatile, multi-tap load box designed to support a wide range of testing conditions. It offers selectable full-load and light-load current taps, enabling technicians to simulate multiple operating scenarios with a single device. With support for common utility voltages and a compact 13 lb. form factor, the 326P provides flexibility without sacrificing accuracy or durability.
The 326X Artificial Resistive Load is optimized for standardized testing environments requiring a fixed, high-current load. Delivering a stable 50A resistive load, the 326X simplifies repeatable test procedures while maintaining the same portability and rugged construction as the 326P.
Both models are designed to operate across common utility voltage ranges and withstand demanding field conditions, making them well-suited for electric utility meter testing, verification, calibration, and troubleshooting workflows.
Key Advantages for Utility Professionals
High-precision resistive load simulation: Supports accurate meter testing and verification in field and lab environments.
Lightweight, portable design: At approximately 13 lbs., both models reduce the physical burden of traditional load boxes and improve field mobility.
Broad voltage compatibility: Supports common utility voltage inputs, enabling deployment across diverse applications.
Flexible testing configurations: Multi-tap capability in the 326P and fixed-load simplicity in the 326X address distinct testing requirements.
Rugged, field-ready construction: Engineered for durability in real-world utility environments.
Compatibility with TESCO test ecosystems: Designed to integrate seamlessly with TESCO’s broader portfolio of meter testing equipment and accessories.
Supporting Modern Utility Testing and Smart Grid Operations
The 326P and 326X are designed to support the evolving needs of electric utilities, from traditional meter testing to smart grid validation and field diagnostics. Their compact design and configurable load capabilities enable technicians to replicate real-world load conditions with greater efficiency and confidence, reducing testing complexity while improving measurement accuracy.
“Utilities require testing tools that balance precision, portability, and reliability,” said Tom Lawton, President & CEO at TESCO Metering. “The 326P and 326X reflect TESCO’s commitment to engineering solutions that align with the realities of modern field and lab operations, delivering dependable load simulation capabilities in a highly practical form factor.”
