Tips: Overvoltage and overcurrent of self-healing low voltage shunt power capacitor
1. Overvoltage
The capacitor should be properly protected by lightning overvoltage and installed close to the capacitor. When capacity is fixed on the motor, in order to prevent the motor from producing excessive high voltage which is self-excited after the power cut off, it is suggested to choose a capacitor with rated current less than the no-load current of motor, generally 90% advisable.
2. Overcurrent
Capacitors cannot operate at a current rate of 1.3 times than the rated current. Overcurrent may be caused by overvoltage of base wave, harmonics, or both. In order to ensure the service life of capacitor, even if the current is within 1.3 times, but still exceed the rated current value, please use caution. Best before and after the installation, it is better to measure the voltage waveform and network features, when there is a harmonic source (for example, large rectifier, inverter, etc.), corresponding measures should be taken to limit (e.g., choose the series reactor) according to corresponding severity of harmonic.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
