Frequently Asked Questions

How does HiDry help reduce operational costs?

By following EU Tier 2 standards, it significantly reduces no-load losses, leading to lower energy bills and a smaller carbon footprint.

Can HiDry be used for renewable energy integration?

Absolutely. It is widely used in wind and solar farms for stable grid connection and medium-voltage power step-up.

What is the maximum voltage HiDry can handle?

The HiDry series is designed for medium-voltage grids up to 52 kV, covering most utility and industrial requirements.

Is remote monitoring available for these units?

Yes, we can integrate temperature sensors (PT100) and communication modules for SCADA or IoT-based monitoring.

What are the insulation classes for HiDry?

Most units are built with Class H (180°C) insulation, providing superior heat resistance and a longer operational life.

Does ABB HiDry require a specialized enclosure?

While standard units are IP00, we provide custom enclosures (IP23/IP31) for indoor protection against dust and water drips.
