Electrical characteristics of medium voltage capacitors (continued) PROTECTION DEVICES FOR "ALL-FILM" MV CAPACITORS (continued) MEDIUM VOLTAGE RANGE There are four protection options for "all-film" MV capacitors: Without internal fuses and external protection by unbalance monitoring With internal fuses and external protection by unbalance monitoring Without pressure monitoring device and external protection by HRC fuses With pressure monitoring device and external protection by HRC fuses Capacitor power and voltage Capacitor connection Capacitor protection The choice between these four options is dependent on the following criteria: Electrical characteristics of the capacitor (power, voltage, connection) Customer's requirements concerning the sensitivity of the protection device The following table gives the possible type of protection for the capacitor and its advantages, according to the above criteria. Associated external protection Advantages All powers and all voltages Single phase Without internal fuse Unbalance P ≥ 200 kVAr and U ≤ 13 kV Single phase With internal fuses Unbalance All powers and U ≤ 12 kV Three-phase Without pressure monitoring device HRC fuses All powers and U ≤ 12 kV Three-phase With pressure monitoring device HRC fuses INSTALLATION CONDITIONS FOR "ALL-FILM" MV CAPACITORS Temperature class Standard: - 25/+ 45°C: - 45°C average over 1 hour - 40°C average over 24 hours - 30°C average over 1 year Protection against corrosion Installation possible: indoor or outdoor Stainless steel case, with one coat of primer and several top coats (RAL 7033) Compatibility with the environment "All-film" capacitors are impregnated with a (PCB-free) biodegradable liquid dielectric. Their installation does not require any particular precautions with regard to the environment. Other temperature classes on request, please consult us 58
