Transmission Line Impedance Analyzer
Model: HLT-300
Transmission Line Impedance Analyzer HLT-300 is a high-precision instrument for testing various high-voltage transmission line parameters in power station, substation or laboratory. The instrument is integrated structure with built-in frequency conversion power module, which can output power by means of frequency conversion voltage regulation. The frequency can be changed to 45Hz or 55Hz. Digital filtering technology is adopted to avoid the interference of power frequency electric field on site, and fundamentally solve the problem of accurate measurement under the interference of strong electric field.
