Differences Between Fixed Wiring Testing and PAT Testing

Understanding the difference between fixed wiring testing and Portable Appliance Testing (PAT) is crucial when it comes to maintaining safety in the workplace and at home. These are two fundamental aspects of electrical safety, helping to prevent electrical accidents and ensure a safe environment. This blog discusses what fixed wiring and PAT testing are and …

Current Transformer Classification based on Four Parameters

One can discern parameters that define their use and function in the electrical circuit
or the transformer’s circuit itself among the many features of transformers. We
therefore identify several factors that characterize the based on the designation of
the circuit and the circuit of the transformer.

3 Methods of testing a diode with multimeter and oscilloscope

Testing a diode

Testing a diode with a digital multimeter in two ways, diode testing portion, and ohmmeter. A diode test is considered passed if it shows low resistance/voltage drop on forward bias and high resistance/voltage drop in reverse bias. A diode curve tracer uses an oscilloscope for VI characteristics graph.
