OMICRON CPOL2 Handheld Polarity Checker

OMICRON CPOL2 Handheld Polarity Checker

The OMICRON CPOL2 is a compact, handheld device designed for verifying the polarity of current transformers (CTs), voltage transformers (VTs), and associated wiring. It operates by detecting a DC-free sawtooth signal injected into the primary side of a transformer, providing clear visual feedback: a green LED indicates correct polarity, while a red LED signals incorrect polarity. This method prevents core saturation and potential protection malfunctions associated with traditional battery-based tests. The CPOL2 is compatible with various OMICRON test sets, including the CMC series, COMPANO 100, CPC 100, and CT Analyzer, facilitating seamless integration into existing testing workflows.
