FAQs
Q1: What is a split-core current transformer?
A1: Split core current transformer is made of high strength PVC shell, fully cast busbar type structure. a split core current transformer is directly stuck on the cable with three sexual rubber rings against the cable and the cable one. The transformer core uses better silicon steel rolled, the secondary wire evenly wound in the core. Transformers for the open and closed structures can be installed without cutting the cable.
Q2: What is the meaning of the circles of the split core current transformer?
A2: On electrical system diagrams, a small circle is often used to represent a winding, and a circle is used to represent a winding. If you have two circles in a series, that means that the open and closed current transformer has two windings. If you have three circles in a series, that means you have three windings.
Q3: What is a split core current transformer error?
A3: Due to the structure of the split core current transformer core and material properties, the current transformer has an excitation current I0, which makes it produces errors.
Tips: Troubleshooting of split core current transformer
- Surface discharge may occur on the CT surface due to unclean insulation material or high humidity. The size and arrangement of the capacitor screen were not consistent with the design requirements. For example, the flatness of the capacitor plate is not uniform, the release of the capacitor plate is less, and the capacitor is broken or misplaced, leading to the failure of the equalization characteristics of the CT. Therefore, when the electric field strength of the local solid insulation surface of the current transformer reaches a certain value, it will cause partial discharge.
- Spark discharge is caused by the transformer metal potential suspension and connection loosening in the warehouse. For example, a loose support nut of the primary winding can lead to wire mesh lead contact, and the shielding aluminum foil of the primary winding may be suspended, poorly welded, or even broken. All these can lead to current transformer failure.
- Failures of increased contact resistance and CT local overheating are generally caused by loose end screen grounding nuts, loose tapping nuts, loose main connection nuts, bolts, and cleats. In addition, improper site maintenance management should also be taken into account. For example, the moisture problem of the transformer may be related to the manufacturer's sealing structure and sealing materials, but it may also be a problem of maintenance management.
