Case Study: Correlative Analyses for Transformer Health
Case Study: Traveling Wave vs Distance Relay Savings
Case Study: UHF PD Amplitude in Transformers

Utilities now face a fast‑moving landscape: smart‑grid upgrades spread, renewable generation rises, and deregulated markets tighten margins. Meanwhile, mature regions—Central Europe, the United States, and Japan—rely on aging transformers, while India and China race to install new capacity to meet surging demand.
In this environment, condition‑based maintenance that uses UHF partial‑discharge detection spots insulation defects early and directs timely, targeted repairs—preserving uptime and protecting budgets.
Economic Environment – The Challenges:
- Smart‑grid technologies and growing alternative generation.
- Deregulated energy markets are placing cost pressure on operators.
- Aging fleets of critical assets in developed regions (Central Europe, the US, Japan).
- Rapid expansion of new installations in India and China.
For more details on how condition‑based maintenance tackles these issues—and on the effectiveness of the UHF technique for partial‑discharge detection and localization in transformers, you can check out the full case study.
