Current Transducers: L01Z100S05 application field and working principle

Current transducers are devices that can be used to measure AC or DC electrical current. These devices enable the measurement of the quantity, power and direction of current flow. L01Z100S05 is a current transducer produced by a German corporation, which has multiple uses in different applications.

Application field

L01Z100S05 current transducer can be used in power distribution, motor control, power conditioning, circuit protection, instrumentation, and controlling isolated loads. It can also be used for energy-saving applications, such as power factor correction and harmonic filters.

The device can measure DC current up to 1000 A. It is suitable for applications involving medical equipment, electrical vehicles, intelligent building systems, renewable energy sources, power distribution systems, solar systems, industrial control systems, and smart grid systems.

Working principle

The L01Z100S05 current transducer works on the principle of Rogowski Integral. It consists of a Rogowski coil and a sense resistor. The Rogowski coil, which is the measuring device, is a coreless roll-wound coil with no ferromagnetic elements. The sense resistor is used to measure the current. The current flow through the coil generates a magnetic field which is then sensed by the coil.

The device works by transforming the measured current into a proportional output voltage that can be read by external instruments. This output voltage is linear to the actual measured current and it is proportional to the frequency and phase of the current too.

The device is designed to measure the current without having to break the current path in the circuit. This an advantage over traditional current-sensing devices such as Hall-effect transducers or shunt resistors, which require a break in the circuit for measuring.

Benefits

The L01Z100S05 is free from zero-point offsets and nonlinearities so it is highly accurate, reliable, and repeatable. It is also lightweight, compact, and easy to install. It has a wide input range and is isolated from the power line due to its built-in galvanic isolation.

The device’s response is also quick, with the measuring process being completed within 35 microseconds. This makes the device suitable for fast dynamic current-sensing applications. The high error rate of the device is also impressive, as it has a maximum linearity error of 0.1%.

Limitations

While the device has many benefits, it does have some limitations as well. The L01Z100S05 is not suited for high-voltage applications since it has a maximum of 600V. Additionally, it can only measure alternating current with a frequency of 50 to 60 Hz.

Conclusion

The L01Z100S05 current transducer is a reliable and accurate device that can be used for a wide range of applications, including motor control, power condition, energy-saving applications, and more. The device works on the principle of Rogowski Integral and it is free from zero-point offsets and nonlinearities. It is also lightweight, compact, and easy to install, making it a great choice for the job.
