Research & Laboratory Solutions

Research & Laboratory Comprehensive Test Solution Overview

Research institutes and university key laboratories focus on cutting-edge R&D of new energy power electronics, electrical materials, energy storage and photovoltaic equipment. During device development, circuit topology debugging, system joint commissioning and failure mechanism research, researchers need high-precision electrical parameter acquisition, power quality harmonic analysis, high-voltage insulation safety verification, tiny leakage current monitoring, temperature field visualization, partial discharge sound source localization and battery aging characteristic testing. Strict requirements are placed on measurement accuracy, long-term data recording, anti-interference performance and research data export.

This comprehensive laboratory test solution fully complies with IEC and national test standards, covering five major research scenarios: material and component evaluation, power electronic converter testing, high-voltage insulation safety test, equipment physical field detection, and basic circuit debugging. It builds full-process measurement capacity from component-level testing to whole-machine system experiments. Relying on a matrix of high-precision measuring instruments, the system supports IV curve testing, harmonic & three-phase unbalance analysis, 4-wire precision low-resistance measurement, 10kV high-voltage insulation testing, microamp-level leakage current capture, thermal distribution imaging and acoustic partial discharge localization. It continuously provides traceable experimental data to support research projects including battery SOH modeling, power device loss analysis, insulation aging mechanism research, and grid-connected equipment compliance pre-test, greatly shortening prototype development and type test cycles.
