Transformer OLTC On Load Tap Changer Parameter Tester
Product Description
On-load tap is the only moving part is connected to the transformer circuit, so there is load tap detection, more and more attention.In the transfer of power equipment and preventive testing of procedures, requiring check-load tap sequence of actions, such as switching time measurement.The instrument is mainly used in measuring the transformer load tap waveform transition, the transition time, transition resistance value of each moment, three-phase over the same period, etc
