The Ferraz Shawmut 68631 Mersen current transformer is a versatile and reliable solution for measuring alternating current (AC) in electrical power systems. This transformer is manufactured by Mersen, a global leader in electrical power and advanced materials, ensuring high-quality standards and expertise.
The 68631 model is a current transformer type 3, which means it is designed for currents up to 3000 Amperes (A) and a ratio of 250:5 Amps. It features a core design with a minimum number of turns in the primary winding and a large number in the secondary winding, resulting in a high accuracy and low power loss. The secondary winding is wound on a bobbin with a sealed epoxy coating, which provides excellent insulation and protection against moisture and contaminants.
The current transformer has a CT Class 0.2 accuracy, which ensures a very low percentage of error in the measurement of the primary current. It operates on a current ratio of 1:250, meaning that the secondary current is 1/250th of the primary current. The maximum voltage that can be applied to the primary winding is 10,000 Volts (V), and the maximum secondary winding voltage is 25V.
The 68631 model comes with a set of secondary terminals that are bolted to the transformer housing. These terminals are rated for a current of 10 Amps and are equipped with insulating bushings to ensure safe and reliable connections. The transformer also features a current tap that is accessible from the outside, allowing for easy calibration and maintenance.
The Ferraz Shawmut 68631 Mersen current transformer is designed for use in harsh environments and can withstand temperatures ranging from -40 C to 70 C (-40 F to 158 F). It is also sealed against dust and water intrusion, making it suitable for outdoor installations and applications in industries such as power generation, transportation, and oil and gas.
In conclusion, the Ferraz Shawmut 68631 Mersen current transformer is a high-performance and reliable solution for measuring alternating currents in electrical power systems. Its features, such as high accuracy, wide operating temperature range, and robust design, make it a preferred choice for various industries and applications.
