BS EN 61000‑4‑12 is a part of the BS EN 61000 multi-series that discusses electromagnetic compatibility.
BS EN 61000‑4‑12 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to ring waves occurring in low-voltage power, control and signal lines supplied by public and non-public networks.
BS EN 61000‑4‑12 on ring wave immunity test is useful for:
The ring wave is an oscillatory transient, induced in low-voltage cables due to the switching of electrical networks and reactive loads, faults and insulation breakdown of power supply circuits or lightning. It is, in fact, the most diffused phenomenon occurring in power supply (high voltage, medium voltage, low voltage) networks, as well as in control and signal lines.
BS EN 61000‑4‑12 enables you to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to ring waves. The test method documented in BS EN 61000‑4‑12 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.
Overall, the test method defined in BS EN 61000-4-12 can help you to ensure that your electrical products will operate safely and effectively in the real world.
