Introduction
TH2819XA is an automatic transformer multi-parameter measurement instrument used for quality control of electronic transformer over a wide range of frequency (20 Hz to 200 kHz). Almost all low-voltage transformer parameters can be scanned, including the primary parameters of inductance L, leakage inductance Lk, turns-ratio Tr, DC resistance DCR, impedance Z, and capacitance (between windings) C etc. and the secondary parameters of quality Factor Q , ESR and phase etc., pin short can also be detected as well.
