What Powertek does

Powertek (Powertek UK Ltd) is a privately held designer and manufacturer of electrical power, voltage, and current measurement instrumentation, headquartered in Reading, United Kingdom. The company produces a broad portfolio of precision hardware instruments including Rogowski coil AC current probes (with ultra-miniature 1.2-1.7mm sense coils), differential voltage probes (up to 40kVp-p), phase angle voltmeters (0.02° accuracy using Discrete Fourier Transform algorithms), wideband power analyzers (DC to 2-50MHz), AC/DC watt transducers, energy meters, and static frequency converters (1kVA to 450kVA). Its technology stack emphasizes physical sensor design, high-bandwidth signal processing, and integration with industrial protocols (Modbus, Profibus, ProfiNet, CAN BUS, GPIB, LabVIEW).

Powertek serves four primary customer verticals: industrial automation (motor drives, process control), energy and utilities (MicroGrid and BESS control via the UFIX-3ph ultrafast sensor), aerospace and defense (400Hz avionics testing, aircraft MRO through the NEACO partnership), and power electronics R&D (GaN/SiC switching analysis). The company operates direct sales and service offices in the UK (Reading), US (Holbrook, NY), and India (Bengaluru), supplemented by a global distributor network of 30+ countries. Revenue is generated through hardware sales and recurring calibration/repair services traceable to UKAS, NIST, NVLAP, and other national standards. The company holds ISO 9001, EN 17025, and FAA Part 145/EASA.145.4703 certifications.
