Prevent insulation breakdown accidents caused by partial discharge and corona discharge occurring in inverter control.
This is a partial discharge and corona discharge testing machine that responds to changes in load capacity through capacitance tuning with continuous sine waves.
Achieving humidity below 30% with dry air! Introducing the humidity requirements and specifications of key standards in CDM testing.
In ANSI/ESDA/JEDEC JS-002-2014, it is required that the relative humidity near the device during testing be kept below 30%. The verification method involves installing temperature and humidity sensors in two locations near the sample to continuously monitor the temperature and humidity, and the test begins when the relative humidity falls below 30%. The AEC standards also explicitly state in the 2019 revision that they comply with ANSI/ESDA/JEDEC JS-002, and it is expected that the demand for low humidity environments will continue to increase in the future. 【Humidity Requirements for Major CDM Test Standards】 ■ ANSI/ESDA/JEDEC JS-002-2018: Relative humidity below 30% ■ AEC-Q100-011 Rev-D・AEC-Q101-005 Rev-A: Relative humidity below 30% ■ JEITA ED-4701/302A (Test Method 305D): Ambient temperature 25°C ± 5°C *For more details, please refer to the PDF document or feel free to contact us.
Compliant with VDE 0434, IEC 60270, EN 50178, VDE 0884, IEC 60747-5-5, UL 1577, etc.
This is for laboratory or on-site measurement of partial discharge in medium and high voltage components in accordance with VDE 0434, IEC 60270, EN 50178, VDE 0884, IEC 60747-5-5, UL 1577, etc. Partial discharge (PD) is a localized discharge that occurs in defects or uneven areas. Partial discharge measurement is a so-called "non-destructive test" used to assess the quality of insulating materials. Unlike pure high voltage testing, the test specimen is not pre-damaged at low PD levels. Partial discharge measurement involves at least one coupling capacitor, measurement impedance, and a partial discharge measurement device (PD meter). The MPS partial discharge test set and PD meter comply with IEC 60270 and IEC 60060. High voltage (Hi-Pot) and partial discharge tests can be conducted in accordance with VDE 0884, IEC 60747-5-5, IEC 60664, IEC 61730-2, UL 1577, and others.
