Measurement of Voltage and Current using C.R.O. (Cathode Ray Oscilloscope)

Trade: Electrician | Semester: II | Marks: 90

Introduction

The Cathode Ray Oscilloscope (C.R.O.) is a very important electronic measuring instrument used to observe and analyze electrical signals. It displays voltage signals in graphical form (waveform) with respect to time. This makes it extremely useful for electricians in testing, troubleshooting, and maintenance work.

🧪 Testing of Transformer Oil

Transformer oil, also known as insulating oil, plays a crucial role in cooling and insulating transformers. Over time, the quality of transformer oil can degrade due to contamination, oxidation, or moisture absorption. Hence, regular testing is essential to ensure proper functioning and longevity of transformers. 🛡️
