XHTX1318 Series Transformer Characteristic Tester is a high-precision, dual-function diagnostic instrument that effectively serves as two instruments in one: a transformer capacity tester and a transformer characteristic parameter tester. Engineered for comprehensive transformer evaluation, it accurately measures multiple power frequency parameters across diverse transformer models — including capacity, type identification, no-load current, no-load loss, short-circuit (load) loss, impedance voltage, and vector group analysis. With ±0.2% measurement accuracy across voltage, current, and power parameters, it is the go-to instrument for power utilities, transformer manufacturers, and testing service providers who require reliable, repeatable transformer diagnostics in the field or laboratory.
