Chroma 19501-K Partial Discharge Tester provides AC High Voltage Testing (Hi-Pot) for the measurement of leakage current and flashover, as well as PD measurement to quantify the charge (pC) from partial discharges in the Device Under Test (DUT). The testing ensures the product's insulation quality and reliability.
Key Features 19501-K:
- Built-in functions for AC Hi-Pot test and PD detection.
- Programmable AC Hi-Pot voltage output: 0.1 kVac up to 10 kVac.
- High accuracy and resolution current meter: Up to 0.01 uA to 300 uA.
- PD Detection Range: 1 pC to 2000 pC.
- Includes High Voltage Contact Check (HVCC) function.
- Standards Compliant: Meets requirements according to IEC 60747-5-5, VDE 0884, and IEC 60270.
- Separate design for measurement and display unit to reduce interference.
The 19501-K is specifically designed for testing high-voltage semiconductor components and highly insulating materials. It uses narrow-band measuring technology and displays the PD results in pC on the screen. It features built-in measurement methods that meet production test requirements for components like optocouplers according to IEC 60747-5-5.
Continuous partial discharge deteriorates insulation material and can lead to safety hazards. Therefore, regulations require PD testing to be performed during production, with the requirement that the discharge must be less than 5 pC under the maximum insulation voltage for optocouplers.
Position in the Product Family
The 19501-K is based on the Chroma 19501 architecture but is an integrated unit with fixed specifications (including 10 kV capability and specific leakage current measurement). It differs from the modular 19501 Base Platform, which can be combined with separate HV modules like the A195005 (5 kV) or A195004 (10 kV) for flexible configuration.
