It is a high-integration precision testing instrument designed for comprehensive performance detection of low-voltage (LV) cabinets, switchgear, and distribution cabinets. Core functions include insulation resistance testing, continuity & loop resistance testing, protection relay (overcurrent/undervoltage/earth fault) testing, on-load switch performance testing, and auxiliary circuit function verification.
Working principle: Connect the device to the LV cabinet’s incoming/outgoing terminals, protection devices, and auxiliary circuits once. The embedded control unit automatically switches test circuits, outputs standard test signals (voltage/current), collects real-time data via high-precision sampling modules, and compares results with IEC 61439, GB 7251 standards to generate qualified test reports. It integrates multiple test functions into one device, avoiding repeated wiring and improving testing efficiency.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
