At present, the most widely used power supply method is solar power supply, but this method is greatly affected by climatic conditions and lacks long-term maintenance-free capability. Laser power has been applied in electronic current transformers and active optical current transformers, but this ty
Current transformer is an important secondary device in the power system. It is widely used in secondary circuits such as metering, measurement, and relay protection. In large current or high voltage occasions, we cannot directly use an ammeter to measure the current of the circuit. It can be measur
Permalloy often refers to iron-nickel alloys with a nickel content in the range of 30 to 90%. It is a very widely used soft magnetic alloy. Through appropriate technology, magnetic properties can be effectively controlled, such as initial permeability exceeding 105, maximum permeability exceeding 10
This power suply CT device is our newly developed product,which is used on 100v-220kv AC transmission line.
In fact, the ammeter measures the current in the circuit, but can we also measure it in the high-voltage line or the circuit with very large current? It is very dangerous in the high-voltage circuit, and the circuit with relatively large current is easy to burn out by directly using an ammeter.
