Outdoor Metering Units from 440V to 33kV
Amrest Electricals Limited manufactures precision-engineered Metering Units for accurate energy measurement across low voltage (LV) and high voltage (HV) systems from 440V to 33kV. They are built for reliability, safety and long-term performance in demanding environments.
3 Phase 4 Wire and 3 Phase 3 Wire
All units are designed for outdoor applications and can be customized with resin cast or oil cooled insulation as per project and operational requirements.
3 Phase 4 Wire metering unit
Designed for systems with a neutral connection, ensuring accurate measurement under both balanced and unbalanced load conditions. Ideal for utilities, commercial and mixed-load applications.
3 Phase 3 Wire metering unit
Suitable for systems without a neutral, commonly used in industrial power distribution networks with balanced load conditions.
Resin cast or oil cooled
Resin cast type
- Maintenance-free and compact design
- High dielectric strength
- Resistant to moisture, dust and environmental stress
- Ideal for modern outdoor installations
Oil cooled type
- Excellent insulation and heat dissipation
- Suitable for higher voltage and load conditions
- Suitable for heavy-duty applications
| Option | Insulation | Best suited for |
|---|---|---|
| 3 Phase 4 Wire | Resin cast or oil cooled | Systems with a neutral; balanced and unbalanced loads |
| 3 Phase 3 Wire | Resin cast or oil cooled | Systems without a neutral; balanced industrial loads |
| Resin cast | Epoxy resin | Compact, maintenance-free outdoor installations |
| Oil cooled | Insulating oil | Higher voltage and load conditions |
Voltage, ratios and accuracy class are defined as per customer/project requirement. Designed with reference to IEC 61869; applicable standards and test documentation are confirmed in the technical offer.
