কিভাবে লাইন ভোল্টেজ ও ফেজ ভোল্টেজ চিনব?

-
লাইন ভোল্টেজ ও ফেজ ভোল্টেজ পরিমাপ করতে হলে চিনতে হবে কোনটি লাইন ভোল্টেজ আর কোনটি ফেজ ভোল্টেজ। ইন্ডাষ্ট্রিয়াল ক্ষেত্রে এই পরিমাপটা খু্বই গুরুত্বপূর্ন্ ।তাহলে আসুন জানা যাক।

একটি ফেজ হতে আরেকটি ফেজের মধ্যবর্তী দূরত্বকে বলে ফেজ ভোল্টেজ এবং একটি ফেজ হতে নিউট্রাল তারের মধ্যবর্তী ভোল্টেজকে লাইন ভোল্টেজ বলে।

About a Transformer

Today my First topic take to Transformer's HT & LT side. We know transformer is a most important device of Electrical Power sector. It's efficiency often 100% because it has no any rotatable parts. Get power self-required. It is known which HT,LT- HT side bushing long and LT side bushing small. Transformer HT(High Tension) side turn to much from LT(Low Tension) side because Primary side 11000 Volts and current lowest from voltage. Secondary side mean LT side voltage less from current. For example: A 100KVA Transformer his Primary side mean HT side current 11000 Volts & current 5.50Amps. His opposite side LT side Voltage 415Volts & Currents 138.4 Amps. With short Circuit current 207.6 Amps. Tansformer has many kind but Notable Power transformer, Distribution transformer. It changes its connection and according to the need current & voltage.
