Megger Group acquires the North American Diagnostic Laboratory business and InsuLogix ® monitoring product line of Weidmann Electrical Technology.

April 1, 2023 — Electrical measurement company Megger continues its expansion into on-line monitoring and added-value services for electrical power utilities with this acquisition. Since 1889, the business focus has been to support the electrical supply industry with test and measurement instruments, providing insight to electrical asset performance.  Megger’s investment into on-line measurements further increases its industry relevance for the future, aligning with the growing movement towards condition-based maintenance philosophies, providing insights for the performance management of electrical assets.

Weidmann’s highly respected oil analysis laboratory services will operate under the AVO Diagnostic Services name, further strengthening its ability to offer on-line and off-line asset condition insights to the electrical power industry.

The latest generation of the InsuLogix® HMA Dissolved Gas Analyzer (DGA) monitoring system becomes a Megger product as part of its growing on-line monitoring range.

Phone numbers remain unchanged and Weidmann email addresses will continue to function while everyone transfers to new @avodiagnostics.com identities.
