FAQ

1. Is the OCT outdoor split-core current transformer waterproof?

The OCT outdoor split-core current transformer has an IP65 protection rating and features a sealed housing with waterproof secondary leads. It is designed for outdoor current monitoring applications. Installation should maintain the integrity of the seals and protect cable connections from water ingress.

2. Can the OCT split-core current transformer be installed without disconnecting the cable?

Yes. Its split-core design allows installation around an existing cable without disconnecting or threading the cable through a closed core. This makes it suitable for retrofit monitoring projects. Installation must follow the applicable electrical safety procedures; a split-core design does not automatically permit live installation.

3. How do I choose the correct OCT model and aperture size?

Select the aperture according to the cable’s outside diameter, including insulation, and check the available installation space. Also confirm the primary current rating, secondary output, accuracy class and rated burden. Provide your cable dimensions and electrical requirements to HEYI for model selection and a matching dimensional drawing.

4. What current ratings and secondary outputs are available for the OCT current transformer?

The OCT series lists primary current ratings from 100A to 1200A, with 1A or 5A secondary outputs for 50/60Hz AC systems. Choose the secondary output to match your meter or monitoring device’s CT input. Confirm the required current ratio and its availability for the selected model before ordering.

5. What accuracy classes and rated burdens does the OCT current transformer offer?

The OCT series lists accuracy classes 0.5 and 1, with rated burdens of 2.5VA, 5VA and 10VA. Available combinations depend on the model and current ratio. When selecting the burden, include both the connected instrument’s burden and the secondary cable burden to ensure the complete circuit meets the CT’s specified operating conditions.
