1. High-Accuracy Instrument Transformers

All ME, MK, and MI units are equipped with Arteche’s precision-engineered instrument transformers:

• Voltage Transformers (VTs) and Current Transformers (CTs) are designed for Class 0.2 / 0.2S accuracy, ideal for revenue metering and grid interconnection points.

• High-performance magnetic cores ensure linearity, minimal phase displacement, and stable accuracy over time.

2. Application-Specific Configurations

• ME Series: Outdoor, self-contained units designed for harsh environments – ideal for substations, pole-mounted setups, and rural grid points.

• MK Series: Modular units with customizable layouts – well-suited for utilities seeking flexible configurations with integrated CT/VTs.

• MI Series: Indoor metering cabinets for urban substations and facilities requiring compact, enclosed setups.

Each series supports three-phase or single-phase configurations, with integrated secondary terminal boxes and test facilities.

3. Standards Compliance & Grid Compatibility

• Fully compliant with IEC 61869, ANSI C57.13, and IEEE standards.

• Designed for seamless integration into SCADA, AMI, and protection relay environments.

• Voltage levels supported: from 12 kV up to 36 kV (and beyond, depending on spec).

4. Reduced Installation & Maintenance Overhead

• Factory pre-tested and calibrated: Plug-and-play deployment minimizes site commissioning time.

• Hermetically sealed, low-maintenance design with oil or dry-type insulation (depending on model).

• Reduced footprint and integrated protection elements streamline civil and electrical works.

5. Long-Term Reliability & Total Cost of Ownership

• Arteche’s metering units are tested for mechanical endurance, dielectric strength, and environmental resilience (IEC 60044, IEEE C37.90).

• Mean Time Between Failures (MTBF) far exceeds industry averages, driving down lifecycle costs.

• Designed for over 30 years of operational life with minimal field servicing.

6. Cyber & Electrical Security

• Secondary circuits and terminal boxes are tamper-resistant and designed with anti-intrusion protection.

• Optional integration with digital metering systems, supporting secure communications via protocols like IEC 61850.
