ACREL 130 x 50II Current Transformer for Electrical Monitoring
ACREL 130 x 50II Current Transformer for Electrical Monitoring is a solid-core AC current transformer designed for high-current measurement in electrical distribution systems. Its horizontal square aperture provides a 135 x 55 mm through opening for suitable busbars or multiple cables. Available with several primary current ratios, it can be paired with electrical measuring instruments and monitoring equipment where an appropriate CT ratio and accuracy configuration are required.
The ACREL 130 x 50II Current Transformer for Electrical Monitoring is designed for current measurement in electrical distribution equipment, switchboards and other AC power systems. Its solid-core construction uses a horizontal square through-hole arrangement, allowing suitable busbars and multiple cables to pass through the transformer.
The 130 x 50II frame has a 135 x 55 mm through aperture and an overall size of 176 x 160 x 50 mm. The manufacturer's technical documentation specifies primary current ratios ranging from 600-800/5(1) A to 2500-5000/5(1) A for this size. The exact ratio, secondary rating and accuracy configuration should be selected to match the measuring equipment and installation requirements.
How it works
- The primary busbar or cable passes through the CT's central aperture.
- Current flowing through the primary conductor produces a magnetic field in the transformer core.
- The current transformer converts this into a proportional secondary current for connection to suitable measuring equipment.
- The selected CT ratio allows high primary currents to be measured using compatible electrical meters or monitoring devices.
Why choose this product
- Large rectangular aperture: The 135 x 55 mm through opening is suited to larger busbars or multiple suitable cables.
- Multiple current ratios: The 130 x 50II configuration is available with several primary current ratio ranges.
- Compact 50 mm depth: The specified 50 mm depth can be useful where available panel space needs to be considered.
- Suitable for electrical measurement: The series is intended for use with electrical measuring instruments and electrical equipment.
Benefits
- Provides a practical method of measuring high AC currents.
- Allows current measurement without placing the full primary current directly through a measuring instrument.
- The rectangular aperture provides flexibility for compatible busbar and cable arrangements.
- Multiple ratio options allow the CT to be specified according to the intended measuring circuit.
