ABB 1YZA93046949 Current transformer

Product Detailed Description:

ABB offers a wide range of current transformers (CTs) used for measuring and monitoring electrical current in power systems and industrial applications. These devices step down high currents to lower, measurable values for connection to measuring instruments, protective relays, and control devices. They come in various types, including wound primary, bar primary, and window type, and are designed for different installation methods and accuracy classes.

Product Parameters (Hypothetical Example):

• Type: Window Type Current Transformer (assuming)

• Primary Current Rating: Varies by model (e.g., 100A, 500A, 1000A)

• Secondary Current Rating: Typically 1A or 5A

• Accuracy Class: Varies by model (e.g., Class 0.5, Class 1)

• Burden (VA): Varies by model

• Rated Voltage: Varies by model (e.g., 0.72 kV)

• Frequency: 50/60 Hz

• Insulation Level: Varies by model

• Mounting: Busbar mounting

Product Advantages (Hypothetical Example):

• Accurate Measurement: Provides precise current measurement for monitoring and control.

• Safety: Isolates measuring instruments from high-voltage circuits.

• Wide Range: Available in various ratings and types to suit different applications.

• Reliable Operation: Designed for long-term reliability in demanding environments.

• Easy Installation: Different mounting options for ease of installation.

Precautions (Hypothetical Example):

• Correct Selection: Choose the appropriate CT based on the primary current rating, accuracy class, burden, and application requirements.

• Proper Installation: Ensure correct mounting and secure connections.

• Burden Matching: Ensure the burden of the connected instrument matches the CT's rating.

• Secondary Short Circuit: Never short-circuit the secondary winding of a current transformer while current is flowing in the primary winding, as this can cause dangerous overvoltages.

• Grounding: Follow proper grounding procedures.

Product Applications (Hypothetical Example):

• Power Metering: Measuring energy consumption.

• Protection Relays: Providing current signals for overcurrent and fault protection.

• Control Systems: Feedback signals for current regulation.

• Load Monitoring: Monitoring current in electrical circuits.

• Substations: Current measurement in high-voltage systems.
