At Powertrac India, we provide power monitoring and protection solutions which are precision engineered. Our HT Current Transformer High Voltage and LT Current Transformer Low Voltage is engineered to guarantee precise measurements, safety of the system and durability in various electrical applications.

Standard Features:
  • Epoxy resin cast construction for superior insulation and mechanical strength.
  • Suitable for 11 kV high-voltage indoor applications.
  • Available in metering accuracy classes 0.5s, 1.0 and 2.0.
  • Protection class options 5P10 and 5P20 for relay protection.
  • Rated continuous thermal current up to 1.2 × In.
  • High short-time withstand current capacity (e.g., 25 kA for 1 sec).
  • Complies with IS: 2705 standards for reliable performance.
Applications Features:

High Voltage HT Current Transformer is designed to meet the high voltage needs at substations, power distribution systems in industries and utility networks where high accuracy in monitoring is required. In the meantime, the LT Current Transformer of Low Voltage is popular in commercial buildings, panel boards, and low-voltage distribution systems to measure the current and manage the load accurately.

Technical Highlights:

Powertrac India current transformers are developed using modern insulation technology, which is associated with insignificant energy loss and increased efficiency. They can easily be installed in switchgear panels due to their compact design. They are capable of supporting metering and protection applications with their strong construction and stability during different load conditions.
