TRANSFORMER & SWITCHGEAR SHIELDING

Managing Electromagnetic Fields in Power Distribution Zones

High-voltage electrical equipment like transformers and switchgear are vital to modern infrastructure, but they also emit intense magnetic and electromagnetic fields that can interfere with nearby systems or pose health and operational risks. At Astra Shield, we engineer bespoke shielding systems to manage these emissions and preserve electromagnetic compatibility across critical environments.

Applications for Astra Shield's solutions include

  • Power distribution zones in hospitals, airports, and commercial towers

  • High-voltage rooms adjacent to MRI suites or control systems

  • Transformer enclosures in data centers, military compounds, and substations

  • R & D and industrial labs requiring low magnetic field tolerance

Engineered Solutions for Field Containment

  • Magnetic Field Mitigation: We apply low-frequency magnetic shielding using silicon steel plates, often layered within walls, floors, or enclosures. Our solutions are based on detailed field simulations and site-specific risk mapping.

  • Electromagnetic Containment: For transient EMI from switching actions, our solutions include bonded metallic enclosures, EMI gaskets, and filtered penetrations. This ensures that signal integrity and equipment performance remain uncompromised

  • Modular or Built-In: Whether integrated into equipment rooms, substation walls, or dedicated vaults, our shielding systems are designed for easy maintenance access, thermal safety, and future scalability

Compliance & Control

  • Our designs are based on IEEE and local power authority standards.

  • We conduct field mapping and simulation to validate exposure limits.

  • We ensure full integration with HVAC, fire safety, and electrical systems.

  • Our shielding is customized by equipment rating, field intensity, and occupancy proximity.
