iLEC SPLIT-CORE CURRENT TRANSFORMER
SCT SERIES
1. Introduction
- The SCT Series Current Transformer is specially designed for easy installation in both new and existing electrical systems. It is primarily used for accurate current measurement at a low cost.
- Due to its relatively large phase angle error and low output power, it is not recommended for power or energy measurement applications.
- Unlike conventional current transformers, which require disconnecting the primary circuit to pass cables or busbars through the transformer core, the SCT split-core current transformer can be installed without interrupting the power supply. This significantly reduces installation time and labor costs.
2. Features
- Compact split-core design for quick and easy installation.
- Double-insulated copper winding ensures safe operation and long-term durability.
- High accuracy and reliable performance.
- Installation without interrupting the power supply.
- Reduces installation time and labor costs.
- Compact design and long service life.
