The quality verification test items for Wound Component consist of AC/DC Hipot tests, Insulation Resistance (IR) test and Impulse Winding test. Chroma integrates the above tests into the 19035 Wound Component EST Scanner series, performing safety tests for motor, transformer, heater related wound products.

The 19035 Series supports a 5kVac/6kVdc high voltage output to conform with withstand test requirements for Wound Components, its maximum output current can up to 30mA. Insulation Resistance (IR) test measurement range is 1MΩ to 50Ω and voltage output can up to 5kV. DCR can measure basic specifications for Wound Component and also check the connection before testing safety withstand.

The 19035 provides OSC and DCR functions to verify if bad contacts or short circuits are happening during test the procedure.

The 19035 is a comprehensive safety tester designed for motor, transformer, heater related wound component requirements. Most of the wound components are equipped with multiple winding such as 3-phase motors, dual winding transformers, etc. Moreover, the wound component needs to use an Impulse Winding Tester for high voltage winding tests to check winding insulation.
