Understanding Cable & Antenna Analysis Part 1

Introduction The cable and antenna system plays a crucial role of the overall performance of a Base Sta­tion system. Degradations and failures in the antenna system may cause poor voice quality or dropped calls. From a carrier standpoint, this could eventually result in loss of revenue. While a problematic base station can be replaced, a cable and antenna system is not so easy to replace. It is the role of the field technician to troubleshoot the…

Transformer Testing with a Megger DLRO10HD

Avoid Unexpected Outages with Regular Testing Regular testing of transformers can help identify problems that reduce system performance and can lead to unexpected outages. The dc resistance of a transformer winding can indicate the internal temperature of the winding when the resistance at ambient is compared to the hot resistance. The ideal test method is to make resistance readings at one minute intervals as the hot winding is cooling, using a
