6 Frequently Asked Questions about “Different types of capacitor external fuses”
Are capacitor fuses capacitive limited?
Most capacitor fuses have a maximum power frequency fault current that they can interrupt. These currents may be different for inductive and capacitively limited faults. For ungrounded or multi-series group banks, the faults are capacitive limited.
How to select external fuse?
Here is the point to select external fuse. (1) Rated voltage : Check the maximum input voltage, and choose higher rating fuse. (2) Rated current : Choose approx. 1.5 ~ 2.0 times from continuous input current. (3) Inrush current* : Calculate Joule heat (I^2t) of inrush current. Time-Lag type (Slo-Blo) should be chosen.
What is a high voltage capacitor fuse?
For high voltage capacitor fuses, this is generally defined as 8.3, 15.5 or 23 kV, the distribution system maximum voltages. Other voltage ratings may be available for special applications. When a capacitor fails, the energy stored in its series group of capacitors is available to dump into the combination of the failed capacitor and fuse.
What is a capacitor fusing factor?
The capacitor must be able to absorb this energy with a low probability of case rupture. Fuses are usually applied with some continuous current margin. The margin is typically in the range of 1.3 to 1.65 per unit. This margin is called the fusing factor.
What is a capacitor fuse used for?
The fuse, by its design, avoids absorbing all of the available energy on the series group. This fuse is used for capacitor banks with a large number of parallel capacitors. It can be used on applications with essentially infinite parallel stored energy, as long as sufficient back voltage can be developed to force the current to extinguish.
What are the different types of fuses?
The fuse element is made of copper, tin or silver. LOW VOLTAGE FUSES: These fuses are used in the relatively low voltage distribution networks. Cartridge fuses: They are very similar to cartridge DC fuses. They consist of a transparent envelope surrounding the fuse element. They can be plugged in (blade type) or screwed into a fixture (bolt type).
