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.
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.
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.
Investing with Powertrac India implies investing in reliability and performance. We utilize the latest manufacturing methods and enforce high standards in quality to produce transformers that are up to the industry standard. Our solutions are designed to suit the needs of customers, so they are as efficient as possible and have a long service life. We offer reliable products with a high degree of innovation and customer satisfaction through the support and technical expertise.
To have effective and precise current measurement, do not doubt the high-performance transformer solutions of Powertrac India.
