ACREL AKH-0.66 100iii AC Current Transformer

The ACREL AKH-0.66 100iii AC Current Transformer is a square closed type measurement current transformer designed for use in low voltage distribution systems. It is used to transform a high primary current into a lower proportional secondary current that can be safely connected to compatible measuring or monitoring equipment.

The 100III construction provides a 102 mm through-hole and is intended for installation around suitable busbars. Acrel specifies a 100 x 10 mm busbar size with one to three bars for the 100III configuration.

How it works

• The primary conductor or busbar passes through the current transformer.
• The transformer senses the primary current through electromagnetic induction.
• The high primary current is converted into a proportional secondary current.
• The secondary output can be connected to compatible meters, monitoring instruments or other measurement equipment.
• Electrical isolation is provided between the primary circuit and secondary measurement circuit as part of the transformer design.

Why choose this product

• Designed specifically for current measurement in low voltage distribution systems.
• Available with several primary current ratios to suit different measurement requirements.
• The 100III format provides a relatively large 102 mm through-hole for suitable busbar installations.
• Supports 5 A or 1 A secondary output configurations.
• Available in accuracy classes including 0.2, 0.5 and 1 according to the AKH-0.66 series specifications.

Benefits

• Provides a practical interface between high-current electrical circuits and measurement equipment.
• Supports electrical current monitoring without connecting the measuring instrument directly to the high-current primary circuit.
• Suitable for integration into low voltage power distribution and measurement systems.
• Multiple current ratio options allow the transformer to be selected according to the measurement circuit requirements.
