Capacitors at low voltage are dry-type units (i.e. are not impregnated by liquid dielectric) comprising metallised polypropylene self-healing film in the form of a two-film roll. Self-healing is a process by which the capacitor restores itself in the event of a fault in the dielectric which can happen during high overloads, voltage transients, etc.
EN 61921:2005 describes the general requirements for the capacitor bank. The most important of them are listed below: Index of protection depends of the place of the installation of a capacitor bank. If the capacitor bank is to be placed in the same place as the main switchgear or utility room next to it, IP 20 is enough.
It helps you to shape up your technical skills in your everyday life as an electrical engineer. In an low voltage electrical installation, capacitor banks can be installed at three different levels - global, segment (or group) and individual.
The purpose of this manual is to assist during the installation, start-up and maintenance of EMK-series low-voltage (LV) capacitor banks with static switching. Carefully read the manual to achieve the best equipment performance. 2.1 Hazards encountered during the installation and start-up of electrical equipment.
The short circuit protection of the capacitors is provided by the switch disconnectors. For the capacitors the fuse link rated current should be 1.6 time of the rated reactive current of the capacitor. In=Q / (Un×√3) where: Q – rated power of the capacitor at rated mains voltage.
Refer to the manual of the specific regulator used in the capacitor bank. This manual is always supplied with the capacitor bank. Make sure that there are no damaged segments on the display (abnormal brightness). Force the manual connection and disconnection of a step.
