kind
1、 Ordinary zero sequence current transformer:
Main technical indicators:
1. Scope of application: Power systems with all 400V-66KV cable feeders.
2. Zero sequence current: The input current on the primary side is 1-36A (customized for orders above 36A), and the output current on the secondary side is 20-300mA.
3. Grid frequency: 50Hz.
4. Secondary load resistance: ≤ ≤ 2.5 Ω.
2、 Specially designed zero sequence current transformer:
In order to meet the needs of power grid expansion in the power industry, our company has successfully developed several high current zero sequence transformers to be used in conjunction with our MLN98 microcomputer line selection device. The system zero sequence currents are 50A-450A and 50A-900A, and the application range has significantly expanded.
3、 Large capacity zero sequence current transformer:
To adapt to neutral point low current grounding systems, our company has successfully developed various high current zero sequence transformers. The zero sequence current range of the system is 300A, 150A, 75A, the secondary current is 5A or 1A, and the capacities are 20KVA, 15KVA, 10KVA, and 5KVA, all of which can be customized for users.
