Voltage Dips, Short Interruptions, and Variations (AC & DC)

Voltage dips, short interruptions, and supply variations represent critical power quality disturbances that can significantly impact the performance of electronic and electrical equipment. For AC systems, these events arise from motor starts, grid switching operations, or fault clearing, leading to rapid reductions in RMS voltage or brief supply loss. For DC systems, similar disturbances occur due to battery switching, converter instability, or transient loading, causing abrupt deviations in the DC bus voltage.

Benefits of conducted Transient Testing

  • Ensures operational stability when equipment experiences sudden reductions or loss of supply voltage.

  • Validates robustness for both AC and DC applications, including grid-connected, battery-based, and power-electronics systems.

  • Prevents system crashes, resets, or data loss during real-world disturbances such as inrush events, switching operations, and grid faults.

  • Improves product reliability in demanding sectors such as industrial automation, automotive, medical devices, IT equipment, and telecom infrastructure.

  • Reduces field failures and warranty costs by identifying susceptibility early in the development cycle.

Our Process and Testing Capabilities

At Stancer Testing-Lab, we are very well equipped to conduct a wide- range of testing with regards to supply voltage variations including voltage dips, short interruptions, long-duration variations, DC ripple content supporting the compliance of products deployed in demanding AC and DC power environments.

Our capabilities encompass single-phase, two-phase, and three-phase AC systems, along with regulated and unregulated DC supply architectures, enabling us to evaluate equipment used in automotive power systems, industrial automation, medical electronics, telecommunications, battery-based systems, power converters, and information technology equipment. This ensures that your devices maintain deterministic performance even during abnormal or unstable mains or DC-bus conditions.

Testing is conducted in our fully controlled EMC laboratory using high performance programmable AC and DC power supplies and specific purpose transient generators to assess compliance of your equipment with regulatory standards including but not limited to IEC 61000-4-12, IEC 61000-4-28, IEC 61000-4-29. and IEC 61000-4-17.
