LFZ1-10 High Voltage Resin Cast Current Transformer Single Phase IEC Standard

LFZ1-10 Casting Resin Indoor High Voltage Current Transformer

Division according to use conditions

In-house voltage transformer: installed in indoor distribution equipment, generally used at and below voltage level;
Home external voltage transformer: installed in the outdoor distribution device, mostly used and above voltage level.

According to the ground running state of primary winding

The voltage Transformer of primary winding grounding: the end of the primary winding of the single phase voltage Transformer or the neutral point of the primary winding of the three phase voltage Transformer is directly grounded;
The UnGrounded voltage Transformer of primary winding: Both ends of primary winding of single phase voltage transformer are insulated to the ground. All parts of the primary winding of the three-phase voltage transformer, including the terminal, are insulated to the ground and the insulation level is consistent with the rated insulation level.

Divide by Magnetic Route Structure

Single-stage voltage transformer: primary winding and secondary winding(as required, multiple secondary windings can be set up on an iron core, the iron core is ground potential. In our country, the single-stage mode is used at and below the voltage level.
Serial voltage transformer: The primary winding is separated into several cells with the same number of turns, each with its own independent iron core, with multiple iron cores, and a secondary winding with high voltage. This type of structure is commonly used in our country in voltage grade.
Combination Transformer: The transformer combined by voltage Transformer and current Transformer group is called combination Transformer.
