Description

. Eltech 11 kV HTCT

• Eltech: Likely the manufacturer or brand name of the current transformer.
• 11 kV: Indicates the high-voltage rating of the transformer, meaning it can safely operate in systems with up to 11 kV (kilovolts) of electrical potential.
• HTCT (High Tension Current Transformer): Used for measuring high current in power transmission and distribution systems. It steps down the current to a lower, measurable level for accurate monitoring and protection.

2. 200/5A Ratio

• 200/5A: This denotes the current transformation ratio. It means the transformer steps down 200 amps on the primary (high voltage) side to 5 amps on the secondary (low voltage) side.
  • Primary current: 200 A
  • Secondary current: 5 A
• This ratio is essential for ensuring that the measuring or protection equipment connected to the secondary side can handle a manageable current for safe and accurate readings.

3. Class 0.2S

• Class 0.2S: This refers to the accuracy class of the current transformer.
  • Class 0.2S indicates that the transformer has a 0.2% accuracy at rated conditions. It means that the error in the current measurement is within ±0.2% of the true current value, making it suitable for high-precision applications such as revenue metering.
  • The S in the class refers to the Special accuracy that is often needed for specific applications like energy billing.

4. DHBVN

• DHBVN: Refers to Dakshin Haryana Bijli Vitran Nigam, a distribution company in Haryana, India. This indicates that the current transformer is likely used in the network operated by DHBVN for monitoring, metering, or protection purposes.
