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.
