Maintenance Planning and Testing
When VIE Flags a Problem: What to Do Next
A VIE alert is a direction, not a diagnosis. Each metric has a specific response: a targeted test, a correlation check, or an immediate action depending on what was flagged and what the trend looks like. This article maps every flag type to its recommended next step.
The VIE Maintenance Integration Guide: What Changes, What Does Not
VIE does not replace your maintenance program. It changes which tests you need, how often you run them, and what triggers them. Some tests become unnecessary. Most become less frequent or more targeted. A few remain exactly as they were. This guide maps each diagnostic test to its new role when VIE is in place.
Transformer Test Cost Reference: What Each Diagnostic Costs and When VIE Replaces It
Maintenance budget decisions require real cost data. This reference provides 2025 to 2026 North American cost ranges for every standard transformer diagnostic, maps each test to what VIE changes about its frequency or necessity, and identifies the tests VIE does not affect. All figures are indicative estimates based on North American market conditions.
How to Set Up a Condition-Based Maintenance Program With VIE
Condition-based maintenance has been a stated goal for transformer fleets for decades. Continuous monitoring data is what makes it achievable at scale. This article explains how to translate VIE's metrics into a working tiered response program — from baseline setup through alert configuration through institutional knowledge capture.
