Internal winding faults resulting from the degradation of transformer winding insulation can be catastrophic and hence expensive. In the new environment of deregulation, utilities therefore are needing inexpensive methods employed to detect such faults in the incipient stage.

The development of an accurate internal fault diagnostic technique for transformers must be based on analysis of quantities from faults scenarios.

Considering the safety of personal, the damage that will occur in the transformer, the consumed time, and related c ....etc

Today, most telephone equipment usea DTMF receiver IC. One commonDTMF receiver IC is the MotorolaMT8870 that is widely used in electroniccommunications circuits. The MT8870 isan 18-pin IC. It is used in telephones anda variety of other applications. When aproper output is not obtained in projectsusing this IC, engineers or technicians needto test this IC separately. A quick testingof this IC could save a lot of time in researchlabs and manufacturing industriesof communication instruments. Here’s asmall and handy tester circu ....etc
