Low-power instrument transformers, manufactured by SVEL Group, are designed to convert high voltage to standard levels, ensuring safe and accurate measurement of electrical network parameters. They are widely used in power systems, power plants, industrial and residential installations for energy metering and equipment protection.

Main Functions:

• Voltage Transformation: Reducing high primary voltage to safe levels for subsequent measurement.
• Circuit Isolation: Providing galvanic isolation between high-voltage and low-voltage circuits, enhancing operational safety.
• Signal Transmission: Delivering accurate data to measuring instruments, protection devices, automation, and control systems.

Classification by Design:

• Support-type Transformers: Installed on a support surface and have cast insulation. Example: OL-SVEL-0.63(1.25)/6(10).
• Support-Pass-Through Transformers: Combine the functions of support and pass-through devices, providing compactness and versatility.

Technical Specifications:

• Voltage Class: 6, 10, 27 kV.
• Rated Power: 630 and 1250 V·A.
• Climatic Version: UHL (moderate and cold climate) and T (tropical climate).
• Placement Category: 1 (outdoor operation) and 2 (under shelter).
