New Professional Solution for Voltage Dips & Short Interruptions Testing up to 1500 V / 100 A
Efficient · Reliable · Safe & Controllable · Accurate Simulation of HV Grid Faults
Background
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.
Technical Challenges
Testing systems for 1500V AC voltage dips, short interruptions, and voltage variations fill a technological gap in new energy (PV/storage), industrial power, and photovoltaic applications, supporting the validation of high‑power equipment in these fields. However, they also introduce challenges in insulation and arc control under high voltage and high current, precise simulation of voltage dips, and the coordination of automated testing with safety protection – mass production imposes stringent requirements on test accuracy and reliability.
