Scope of application
It is used to measure the transition waveform, transition time, transient resistance value of the on-load tap changer of the transformer, and the three-phase consistency.
Performance characteristics
High degree of intelligence;
The instrument is small in size, light in weight and strong in anti-interference ability;
Two test currents are optional, which is convenient for measuring transition resistance in different ranges.
