11 KV HT Metering Cubicle with CTs and PTs – Overview

1. Description:

An 11 kV High Tension (HT) Metering Cubicle is a crucial component in electrical distribution systems. It is designed to measure electrical parameters such as voltage, current, and power factor in high-voltage applications.

Components:

• Metering Cubicle:
  • Houses the metering equipment and protection devices.
  • Designed to ensure safety and reliability in measuring high voltage.
• Current Transformers (CTs):
  • 3 Nos. CTs: These are used to step down the high current to a lower value suitable for metering.
  • Class 0.2S: Indicates a high accuracy class, meaning these CTs can provide accurate current readings with minimal error.
• Potential Transformers (PTs):
  • Used to step down high voltage to a measurable level.
  • Class 0.2S: Indicates that these PTs also offer high accuracy for voltage measurement.

3. Specifications:

• Voltage Level: 11 kV
• CTs and PTs Accuracy Class: 0.2S, meaning they have a maximum permissible error of ±0.2% at rated conditions.
• Manufacturer: Concord (known for producing reliable electrical components).
