IEC 61000-4-19: Test for Immunity to Conducted, Differential Mode Disturbances and Signaling
IEC 61000-4-19 tests the frequency range 2 kHz to 150 kHz at AC power ports. This standard defines test waveforms, range of test levels, test equipment, test setup, test procedures, and verification procedures.
IEC 61000-4-19 tests are intended to demonstrate the immunity of electrical and electronic equipment operating at a mains supply voltage up to 280 V (from phase to neutral or phase to earth if no neutral is used) and a frequency of 50 Hz or 60 Hz when subjected to conducted, differential mode disturbances such as those originating from power electronics.
IEC 61000-4-19 mentions the following disturbances, sources, and victims
Disturbances sources:
Inverters (e.g. elevator drives, ski lift drives, PV installations)
Smart meters with PLC data transmission
Switched-mode power supplies (e.g. in compact lamps, computers, TVs)
UPS
Variable speed drives (e.g. heat pumps)
DVD players
Victims - with degraded performance or malfunction
Smart meters with PLC data transmission, solid-state meters;
Touch-dimmer lamps (TDL)
Communication systems (e.g. Ethernet-system, routers)
Contactless card readers, credit card terminals
Alarm systems
Electronic controls (e.g. heating systems, street lighting)
Household appliances (e.g. coffee machines, ceramic hobs, washing machines)
IEC 61000 Test Equipment for Section 4-19
IEC 61000 test equipment for section 4-19 consists of generators, current transformers and CDNs, depending on whether you are performing a voltage or current test. The following diagrams represent the test setups for each type of test.
