Inductive Power Supply Projects

  • July 14. 2022
With the rapid development of economy, the electricity demand increasing, the power stability & uninterrupted are more and more important. It's imminent to online real-time monitoring on high-voltage transmission lines to guarantee the safe and stable operation of transmission lines.  The high voltage inductive power supply is the best choice for online equipment functions, because is suitable for different climates, stable&reliable power supply, maintenance-free operation. Today, let’s talk about the inductive power supply projects:

Rogowski Coil (measurement range up to 3000A)


1. Hollow Rogowski coil

2. Measurement current: Max. 3000A

3. Diameter 0.3mm enameled wire, 500 turns

4. Lead wire length 15±2 cm (22AWG silicon rubber copper cable )

5. Self resistance 7.8Ω±2 0%, Self inductance 520µH±2 0%@1V 1KHz

6. Split type

7. CT case material: PC+ABS ,High working temperature ,ultraviolet-proof ,and anti-aging.


Rogowski Coil measurement card (KLS3000-2.5)


1. Current input: 0~3000A. Provide high accuracy output with multi ranges.

2. Full range output 2.7V

3. Make integral with differential signal send by Rogowski coil , restore the waveform, and switch to the right effective value.

Measurement range and analog switch instruction

Output range in RMS is 0~2.7V. 0V means 0A input. 2.7V is the Maximum in a range.The meter will switch to next range when output in RMS higher than 2.7V ,and will come back the previous range when output in RMS lower than 1.35V.

Dimensions and pin definition
