FUNCTIONS   Hi-Pot – AC 5kV/100mA – DC 6kV/20mA.    Insulation – 5kVmax – 1MΩ-50GΩ.

APPLICATIONS

Motors : The 19055 Series Hipot Analysers with 500VA output rating can be used to test and analyse the withstand voltage of high power and leakage current for the products like motor stators and rotors with high parasitic capacitances. Corona detection can be used for turn-to-turn or turn-to-ground test to avoid winding insulation failure from corona discharge.

Transformers .

When using a power transformer under the normal voltage, a primary side corona discharge could cause the adjacent components to be damaged. The function of Corona Discharge Detection (CDD) of 19055-C can be used to detect this and to improve the product quality.
High Voltage Capacitors, Photocouplers & Insulation Materials

If any gaps, voids or impurities appeared when doing moulding in the manufacturing process, the insulation capability may be affected. The Corona Discharge Detection (CDD) equipped by 19055-C is able to detect if there is any corona discharge to enhance the product quality. Chroma 19055 Series Hipot Analysers are designed for Hipot tests and analysis.

The 19055-C has not only the AC/DC/IR tests but also a new measurement technology – Corona Discharge Detection (CDD) that can detect the following via the Discharge Level Analysis (DLA).
