CURRENT TRANSFORMER(CT) About

CT IS USED FOR SENSING THE CURRENT AMP METER DISPLAYS CURRENT WE CAN KNOW ALL THREE PHASE CURRENT IF THERE IS UNBALANCE CURRENTBWE CAN BALANCE IT APFC RELAY WORK ON THE BASIS OF CURRENT SENSED BY CT

High Accuracy and Safety Compliance

Designed according to international IEC/IS standards, these current transformers provide highly accurate readings, with Class 0.5, 1.0, or 3.0 options to suit a range of metering and protection needs. Flame retardant, insulated polycarbonate bodies and high-grade thermoplastic insulation ensure superior safety and long-lasting durability for reliable use in indoor environments.

Versatile Application and Easy Installation

Our CTs accommodate both single-phase and three-phase applications, with flexible installation options for vertical or horizontal panel mounting. Terminal/screw clamp connectors simplify panel integration, and a wide inner diameter window (30-50mm) allows for easy fitment over busbars or cables in various panel layouts.

Low Maintenance and High Efficiency

Engineered for efficiency (>98% at rated load), the CTs consume less than 2.5 VA and resist overheating in compliance with IEC thermal endurance standards. Their matte, smooth surface finish and self-extinguishing materials minimize maintenance requirements, making them cost-effective and reliable for long-term use.

FAQ's of CURRENT TRANSFORMER(CT):

Q: How do I select the correct current transformer model for my panel?

A: To choose the right current transformer, first determine your primary current (50A to 1000A) and select the corresponding model. Also, consider your required accuracy class (Class 0.5, 1.0, or 3.0), secondary output (1A or 5A), and ensure the window size accommodates your busbar or cable.

Q: What standards do these current transformers comply with?

A: These CTs are designed in accordance with IEC/IS standards and feature Class 0.5, 1.0, or 3.0 accuracy. They also meet insulation (3kV for 1 minute), IP20 indoor safety, and flame retardant requirements for robust and compliant operation.

Q: Where can these current transformers be installed in my system?

A: These CTs are suitable for installation in electrical panels, with mounting options for both vertical and horizontal orientations on busbars or with panel fitment. Indoor applications are recommended due to their IP20 rating.

Q: What benefits do these CTs offer for energy metering and monitoring?

A: With high accuracy, low energy consumption (<2.5 VA), thermal endurance, and efficient load sensing, these CTs ensure reliable and precise energy monitoring and protection in both industrial and commercial settings. They also feature low maintenance requirements and high operational efficiency (>98% at rated load).

Q: How do I connect the CT to my meter or protective relay?

A: The CT features screw clamp terminals for secure secondary connection. Simply connect the secondary output wires (1A or 5A as specified) to your meter or protective relay per the wiring instructions, ensuring correct orientation for accurate readings.

Q: What is the typical response time and why is it important?

A: These CTs deliver a response time of less than 1 millisecond, which ensures timely and accurate fault detection or load monitoring, helping protect critical electrical systems from delays in metering or protection functions.
