Protection devices for «all film» medium voltage capacitors

 

 

Les différentes possibilités de protection des condensateurs haute tension «tout film»

There are 4 possibilities to protect "all film" MV capacitors :

- Without internal fuses and external protection by un balance monitoring
- With internal fuses and external protection by un balance monitoring
- Without pressure monitoring device and external protection by HRC fuses
- With pressure monitoring device and external protection by HRC fuses

The choice is dependent on the following criteria :

- Electrical characteristics of the capacitor (power, voltage, connection)
- Customer's requirements concerning the sensitivity of the protection device
