Given the different functional requirements of grid protection systems, testing capabilities require a higher level of sophisticated testing hardware and software to analyze the operation of the entire protection system (or individual protection components) under "real life" situations. Similar improvements in simplifying the user interface and software control of test instruments are further necessary to meet these expanding test capabilities. Rest assured, no matter how complex, every aspect of relay testing can be easily handled with Weshine®'s comprehensive line of Relay Switch Tester (VS-JB900 series). Plus, whether you're testing traditional electromechanical relays or modern IEC 61850 networked devices, our rugged products deliver the high power you need while still being portable for practical testing.

Weshine Transformer DC Resistance and Turns Ratio 2 in 1 Tester combines DC resistance, TTR and vector‑group testing in one compact unit. Favoured for tenders, bulk & trial orders by OEMs, utility contractors and substation crews, it gets full pre‑sales, technical and after‑sales support. With 3‑phase simultaneous test, auto‑magnetization, touch screen, printer and multi‑interfaces, it reduces rewiring and provides solid data for acceptance and maintenance reports.

Weshine factory's quality VLF Tan Delta Test System is an integrated ultra-low-frequency cable test unit for medium-voltage cable withstand testing, dielectric loss factor testing, sheath testing, sheath fault pinpointing, and leakage current measurement. It outputs 0.1 Hz sine wave voltage up to 24 kV RMS or 31.8 kV RMS depending on configuration, and measures tan delta at 0.1 Hz. The system fits power utilities, cable maintenance crews, electrical contractors, manufacturing plants, power stations and high-voltage testing labs.
