LZM-4D type intermediate converterDetailed product description:Column tabs
The LZM-4D intermediate converter is an autotransformer winding structure, suitable for bus differential protection and transformer differential protection in power systems. It can effectively compensate for unbalanced currents caused by different current ratios of current transformers, thereby ensuring the normal operation of the protection device.

The LZM-4D type intermediate converter belongs to a centralized configuration structure (i.e., four or fewer current transformers with the same or different transformation ratios only need to be configured with one set of intermediate converters. This type of product has eight commonly used current ratio taps, which has strong universality and is easy to adjust the corresponding current ratio in conjunction with changes in system operation mode)
