Benefits of 20-35kV Current Transformer

High Precision
20-35kV current transformers are highly appreciated for their exceptional accuracy in measuring current. These devices provide precise and reliable readings under varying load conditions.

 

Versatility
Another advantage of a current transformer is its versatility. It is used for various applications, from monitoring power consumption to protecting electrical equipment in renewable energy systems and industrial processes.

 

Safety Isolation
These devices offer electrical isolation between the secondary and primary circuits. This isolation ensures safety and prevents high currents from reaching monitoring and measuring equipment.

 

Durability
Current transformers have a robust design, making them long-lasting and able to withstand harsh environmental conditions.

 

Easy Installation
These devices are also known for their easy installation and simple operation. They are also easy to maintain.

 

 

The Working Principle Of 20-35KV Current Transformers

Electromagnetic current transformers (hereinafter referred to as current transformers) are widely used in power systems. Its working principle is similar to that of a transformer. The ratio of the primary and secondary currents of the current transformer is called the rated mutual inductance ratio of the current transformer.

 

Current transformers (CTs) are used to measure the current in a circuit. They take the current in a circuit and convert it into a signal that can be used in measuring devices such as ammeters, wattmeters, and power monitors.

 

CTs work by allowing the current in a circuit to pass through a coil, which creates a magnetic field. The field strength is proportional to the amount of current flowing through the coil. A secondary coil is placed around the primary coil and the magnetic field of the secondary coil is proportional to the magnetic field of the primary coil. This secondary current is then sent to a measurement device for reading.

 

CTs are used in a variety of applications, including power system protection, motor control, and energy management. They are also used in industrial and commercial environments to monitor energy usage and ensure safety.

Precautions for using 20-35kV Current Transformer

 

 

The secondary side of the current transformer can not be short-circuited at work. In normal operation, the secondary side of the current is very small, close to the open circuit state, when the secondary side of the short circuit, the current is very large (secondary impedance is very small) will burn equipment.

Current transformer's secondary side must be grounded at one end to prevent a secondary side breakdown, high voltage into the secondary side, endangering personal and equipment safety.

Current transformer wiring, should pay attention to the polarity of the terminals on the first and second sides. To ensure the accuracy of the measurement.

Current transformer of the first and second sides should usually be equipped with fuses as short-circuit protection, while the primary side should be equipped with an isolation switch for safety maintenance.

The primary side is connected to the line.

FAQ

 

 

Q: How to check if a current transformer is working?

A: Mechanical Check and Visual Inspection.
Insulation Resistance Test.
Polarity Test.
Secondary/Loop Resistance Test.
Burden Test (optional test)
Magnetization Curve Test (optional test)
Turns Ratio Test (optional test)
Primary Injection Test.

Q: What happens when a current transformer fails?

A: Failure to Produce Output: A CT may fail to produce output due to a short circuit or an overload beyond its capacity. Inspect the CT for signs of damage or overload and replace it if necessary. Saturation occurs when a CT is exposed to current levels beyond its design limits, causing distorted output.

Q: What should you never do with a current transformer?

A: What Should You Never Do with a Current Transformer? A CT should never be left open when energized, as the secondary will produce dangerously high voltage. Such high voltage can destroy insulation, cause electric shock, or damage other connected devices.

Q: What is the lifespan of a current transformer?

A: After the transformer has been in service for about five years, owners expect to see a reliable life of up to about 30 years. After 30 years, the failure rate starts increasing rapidly.
