The main purpose of measuring DC resistance is to check the following aspects of the transformer:1. Whether the welding or mechanical connection at the winding wire connection is good, and whether there are any welding or connection defects.2. Whether the connection between the lead and the sleeve,
Opening and closing timeDetect the time required for the opening and closing actions of circuit breakers or switches to ensure compliance with standard requirements, and determine the response speed and stability of the mechanical transmission mechanism.Synchronization (three-phase synchronization)M
1. Multiphase high-precision output capabilitySix phase independent output: It can simultaneously output six phase current (0-100A) and six phase voltage (0-120V), simulating multiphase fault scenarios in complex power systems (such as three-phase unbalance, differential protection, busbar protectio
