About AcuCT S77 Series
What is a solid-core current transformer?
A solid-core current transformer is designed with a permanent closed core. Sometimes called a "toroidal" or "donut" current transformer, the solid-core design makes this type of current transformer extremely accurate and they are often selected for revenue-grade applications, particularly for installations in new construction. Because the core is sealed against dust or debris, durable solid-core CTs can often out-perform other sensors in challenging settings.
