Název v původním jazyce

Determination of the Value of the Capacitive Earth-Fault Current in Distribution Networks Operated with Isolated Neutral Point

Popis výsledku v původním jazyce

The new indirect method of measurement and calculation of the phase-earth capacity in networks with isolated neutral point is based on creation of a short-term phase capacity asymmetry in the network. The value of the phase earth capacity in the networkcan be determined using the voltage ratio in the network and the capacity value of the connected capacitor. When expanded, the method can be also used for the leakage current estimation. Furthermore, this method can be applied to periodic controls of theearth capacitive current value. For the evaluation of the phase earth capacity, a single-purpose automation can be used and thus the whole process of measurement and evaluation is conducted at a defined period (at a given hour, day, month...) or on operator's command.
