What AVO Diagnostic Services does

AVO Diagnostic Services is a North American transformer diagnostic laboratory services company headquartered in Dallas, Texas. Founded circa 1993 as part of the Weidmann Group and acquired by Megger Group on March 31, 2023, the company operates 9 laboratory locations across the United States (Bensalem, Indianapolis, Rancho Cordova, Waukesha, Pearland), Canada (Burlington, Calgary, Dorval), and Mexico (Coahuila), with the Mexican operations conducted through a dedicated subsidiary. The company provides comprehensive insulating oil and fluid testing for transformers, OLTCs, breakers, regulators, reactors, bushings, and oil-filled cables, including Dissolved Gas Analysis (DGA), moisture via Karl Fischer titration (ASTM D1533), interfacial tension, acidity, dielectric strength (ASTM D877, D1816), power factor, furanic compounds, methanol/ethanol, viscosity, and PCB analysis. All laboratories hold ANAB accreditation and adhere to IEEE diagnostic standards and ASTM testing methods.

The portfolio extends beyond lab testing to include equipment diagnostic evaluations, outsourced laboratory services for operators seeking cost reduction, and engineering support providing written condition assessments and fleet health summaries. The company also sells specialized sampling hardware such as serialized Glass Sample Saver Syringes, Tedlar PVF gas sampling bags, and the Safe Sample Kit (SSK) for outage-free pad mount access. Digitally, AVO offers the AIM (Asset Information Manager) customer portal for accessing test results and asset records, and the Megger Transformer Intelligence Center (MTIC), a software platform that aggregates data from Megger, AVO Diagnostics, and IPS to deliver risk ratings, condition scores, lifecycle forecasts, and Critical DGA Alert notifications for transformer fleet management.

The business model is primarily professional services and managed services sold enterprise-style to power utilities, industrial operators, and renewable energy asset owners through direct sales, website inquiry forms, the AIM portal, and engineering consultation. Pricing is not publicly disclosed and is custom-quoted per engagement. Primary customer segments are power utilities and industrial operators managing electrical infrastructure, with an emerging focus on renewable energy transformer assets. The company markets through its Knowledge Hub (educational content), LinkedIn and Facebook channels, and industry events such as RE+ 2026, and is positioned within the broader Megger Group ecosystem alongside AVO Training and PowerDB.
