Mehta Tech stands at the forefront of innovation, earning multiple patents for our exclusive technologies. We transformed the traditional digital fault recorder (DFR) into a versatile device that not only gathers and processes data but also delivers calculation results for operations, automation, and visualization needs.

Our modular design makes it simple and cost-effective to upgrade, ensuring our systems stay ahead with the latest hardware and software advancements. Mehta Tech’s digital fault recorders are renowned for their outstanding reliability over time.

Our advanced systems meet and exceed PRC-002-5 and PRC-028-1 standards for fault and disturbance monitoring. They also fully comply with IEEE C37.118, offering continuous recording and phasor streaming as standard features.

Our multifunction DFR/PMU products support local storage of high-speed recordings initiated by trigger detection, slower-speed continuous recording, and phasor data streaming. Using versatile facilities to select parameters allows our users to configure the installation to meet site and application requirements by combining the following functions: DFR/SOE Digital Fault and Event Recorder, DDR Dynamic Disturbance Recorder, DME Disturbance Monitoring Equipment, PMU Phasor Measurement Units.

Flexibility: Mehta Tech develops and maintains configurable and adaptable designs to create customer and site-specific implementations.

Upgradeability: Ownership of the hardware, software, and architecture IP allows installed systems to be upgraded, resulting in the lowest lifetime cost within the industry.

Reliability: “Utility Grade” ruggedized designs are built and tested to last.

Mehta Tech’s products monitor disturbances in various facilities: 500kV transmission substations down to distribution level substations, nuclear, fossil fuel, and hydroelectric generating plants Stations with connections to wind farms, renewable generating facilities, Petrochemical, and Silicon Fab plants.

With over 2,000 large-scale DFR installations monitoring our customers’ critical sites, customer support is essential to our activities.

Our customers include large and small investor-owned utilities, Public Power companies, REAs, municipals, and industrials. Our business relations with many of these organizations are long-term customers, spanning over forty years.

Our customers trust Mehta Tech’s capability to provide the following functions securely, accurately, reliably, and steadfastly, creating worry-free, long-life solutions supported throughout the years. Incorporating modular construction makes upgrading for more advanced applications easy to do in the field or our factory.
