In conjunction with a protection device and supply meter, molding type current transformers are used to convert enormous current into manageable current.
As a sort of transformer, a current transformer (CT) is used to increase or decrease an alternating current (AC). It generates a secondary current that is proportionate to the primary current.
Instrument transformers include voltage, potential, and current transformers. Instrument transformers reduce the huge voltage or current values to smaller, standardized values that are simple for measurement devices and safety relays to manage. Measurement or protection circuits are isolated from the high voltage of the primary system by the instrument transformers.
The global molding type current transformer market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Class 1… / 5 A molded case current transformer by Janitza. If high currents need to be recorded and processed further, molded case current transformers are employed.
The primary circuit for the plug-on current transformer is formed by the line to be measured (conductor rail or wire), which is fed via the window opening. Current transformers with molded cases are typically mounted on conductor rails.
Droplet-tightness can be attained through extra potting, and mechanical loading can increase shock and vibration resistance (IEC 68). The most popular and economical type of current transformer is this one. However, during installation, the principal conductor must be cut off. Therefore, new system installations most frequently employ this type of transformer.
