Applications

Motor: The 19055 and 19055-C Hipot Analyzers with 500 VA output rating can be used to test and analyze the withstand voltage of high power and leakage current for products like motor starters and rotors with high parasitic capacitance. Corona detection can be used for turn-to-turn or turn-to-ground test to avoid winding insulation failure from corona discharge.

Transformer: When using a power transformer under the normal voltage, a primary-side corona discharge could cause the adjacent components to be damaged. Thus, Corona Discharge Detection (CDD) of the 19055-C can be used to detect discharge and improve the product quality.

High Voltage Capacitor, Photocoupler & Insulation Material: During manufacturing, gaps, voids or impurities can adversely affect insulation capability. The Corona Discharge Detection (CDD) technology in the 19055-C will detect corona discharge, allowing R&D engineers to detect components with poor insulation.

Corona Discharge Detection (CDD): The 19055-C not only has the AC/DC/IR tests, but also a new measurement technology - Corona Discharge Detection(CDD). CDD can detect the following via the Discharge Level Analysis (DLA):
•  Corona discharge Start Voltage (CSV)
•  Flashover Start Voltage (FSV)
•  BreakDown Voltage (BDV)
