In the aviation industry, airborne electrical systems are rapidly evolving toward higher voltages, higher power, and multiple architectures. 14V/28V/270V/540V voltage platforms coexist, imposing extremely stringent requirements on power supply stability, waveform quality, and dynamic response.

In the aviation industry, airborne electrical systems have always been held to extremely stringent requirements for power supply stability, waveform purity, and immunity performance. International and domestic aviation standards such as MIL‑STD‑704F, GJB 181 series, RTCA/DO‑160G, and HB 20326.8 impose clear mandatory specifications for ripple, harmonics, transient behavior, and load response of airborne DC power supplies.

With the rapid advancement of vehicle electrification and intelligence, the operational stability of on‑board electronic equipment directly depends on its ability to withstand various transient events from the vehicle’s power supply.

With the continuous upgrading of EMC standards in aviation, railway, industrial electronics and other fields, accurate measurement of alternating current and transient pulse current has become a critical part of verifying the electromagnetic compatibility of equipment during conducted susceptibility (immunity) testing.

With the rapid advancement of industrial electrification and energy digitization, voltage dips and short interruptions caused by grid disturbances and sudden load changes have become a primary cause of electrical equipment malfunction, shutdown, and even damage. The voltage immunity of equipment directly determines the safety and continuity of system operation.

With the rapid advancement of vehicle electrification and intelligence, the 48V electrical system has become the mainstream core architecture for hybrid vehicles and high‑power onboard equipment.

The 1500V AC voltage level has become a key development direction in new energy, industrial power, photovoltaic (PV), and energy storage applications, offering the benefits of high power transmission and low losses. Voltage variations caused by grid faults or load changes can easily lead to equipment failure, making rigorous voltage dip testing a critical safeguard for product reliability.
