The quality verification test items for Wound Components consist of AC/DC Hipot tests and Insulation Resistance (IR) tests. Chroma integrates the above tests into the Hybrid 19035 Wound Component EST Scanner series to perform safety tests for motor, transformer, and heater related wound products. The wound component manufacturers performing quality verification testing will not only have reliable quality, but also can control product quality efficiently.
Flashover Detection
Chroma 19035 has the same Flashover detection as other Chroma EST testers. Flashover is the electrical discharge generated by high electrical fields inside or on the surface of insulation materials that cause the DUT to lose its insulation characteristics and form a transient or discontinuous discharge. It can cause a carbonized conductive path, or damage the product under test. Flashover cannot be detected by monitoring leakage current only. The change rates of test voltage and leakage current must be monitored in order to detect flashover, as its detection is one of the most indispensable test items for electrical safety testing.
Ground Fault Interrupt (GFI)
The requirements for test environments indicates that test equipment is to be equipped with an auto interrupt device, so Chroma built in a Ground Fault Interrupt (GFI) function. When the current meter A1 and A2 detect a difference (i2-i1 = iH ) between the value i1 and actual i2 test current over high, this device can cut the power transiently for protecting against electrical shock to the operator. It is not only according to safety standards but also provides additional safeguards for test personnel.

The 19035 Series is a comprehensive safety tester designed for motor, transformer, and heat related wound component tests. Most wound components have multiple windings, such as 3-phase motors and dual winding transformers. With 8-channel scanning ability the 19035 can measure multiple test points in one test instead of switching test points manually. This reduces test time and labor cost immensely.
