HGQB-C CT PT calibrator, is a novel automated detection equipment, which uses advanced electronic technology to collect and decompose the error signal of transformer directly, after appropriate operation, the percentage points, in-phase error and quadrature errors of transformer are displayed in digital at the same time. The instrument is widely used in measurement, power supply, instrument transformer manufacturers and other department. It is an ideal instrument for instrument transformer testing.
Overview
Product Introduction
HGQB-C CT PT calibrator is a novel automated detection equipment which uses advanced electronic technology to collect and decompose the error signal of transformer directly after appropriate operation the percentage points in-phase error and quadrature errors of transformer are displayed in digital at the same time. The instrument is widely used in measurement power supply instrument transformer manufacturers and other department. It is an ideal instrument for instrument transformer testing.
