🚀 Product Description
PRODUCT INTRODUCTION
The zero-sequence current transformer is suitable for small grounding current systems with a rated frequency of 50/60Hz and rated voltage of 35kV and below. It is used in conjunction with DD-11/60 or DD-1/60 type relay protection and signal devices for residual (zero-sequence) current detection and grounding protection. At the same time, it activates the device components to achieve protection and monitoring.
This series of zero-sequence current transformers are cable-type resin-cast insulated indoor products. They feature an open-closed type and epoxy resin-cast structure. They can be divided into two parts and then combined into one during installation, which is highly convenient for field setup.
