Read about TLAR CTs, when to use them, and how they differ from Flex CTs.

TLARs are PMI’s iron core CT (Current Transformer) clamps, available in various probe and channel configurations. These clamps are used for lower range current measurements, with ranges of 20A or 200A. Most of PMI’s recorders offer the ability to measure current via user selectable Flexible CTs or iron core TLAR clamps. This white paper explains how current transformers work generally and how PMI TLAR CT work specifically, and tips for TLAR use.
