Rogowski coil is an AC current sensor widely used in various situations that require measuring AC current. The following are some of the main uses of Rogowski coil:
Current measurement: The Rogowski coil can be directly placed on the measured conductor to measure AC current, suitable for measuring AC current over a wide frequency range. It has no special requirements for the conductor or size, and has fast instantaneous response ability. It is particularly suitable for measuring high-frequency and high current, as well as in situations where traditional current measurement devices such as current transformers cannot be used.
Power system protection: Rogowski coil can be used for power system protection, such as overcurrent protection of equipment such as transformers, busbars, cables, and circuit breakers. It can quickly and accurately detect overcurrent and quickly cut off fault current through protective devices, protecting the power system from damage.
High voltage insulation testing: In high voltage insulation testing, the Rogowski coil probe is used to continuously detect various transient changes during the process. High voltage discharge is the main cause of insulation deterioration in power equipment, and Rogowski coil can detect these changes in a timely manner, providing important guarantees for the safe and stable operation of the power system.
RF pulse current test: The Rogowski coil can effectively monitor and detect current in large AC power supplies and US level pulse auxiliary power supply systems for giant plasma, and can measure pulse or large AC currents up to several megaamperes. This makes it widely applicable in fields such as plasma research, pulsed strong magnetic fields, and laser sources.
Detonation and transient testing: Rogowski coil are widely used for testing various transient pulse currents related to detonation physics. Rogowski coil play an important role in the driving system of electromagnetic guns, high-energy laser equipment, ultra high speed launch devices, X-ray imaging systems, electromagnetic orbit launch systems, and power supply systems.
In summary, as an AC current sensor, the Rogowski coil has broad application prospects and important practical value. With the continuous development of technology, the application fields of Rogowski coil will continue to expand.
