6 FAQs about [690v box transformer circuit breaker energy storage circuit]

Why do I need a 690 V transformer?

First of all, the need to install more 690 V transformers due to the derating of switching devices fault duty when operating at 690 V. Secondly, it is necessary to make use of a 400/230 V system to feed small motors (below 0.18 kW) and particular users (i.e. lighting, heaters, etc.).

How much power does a 690V motor have?

Moreover, for 690V level, the manufacturers certify motor protection co-ordination (i.e. fuses and contactors, moulded-case circuit breaker and contactors, limitors and contactors) only up to 50 kA and for motor size up to 350 kW.

What is MV/LV transformer electrical substation?

t can be defined as a transforming, conversion, transmission or distribution substation. A MV/ LV transformer electrical substation consists, therefore, of the set of devices dedicated to the transformation of the voltage supplied by the distribution network at medium voltage (e.g. 20 kV)

Should 400V be replaced with 690V?

The study identified size and motors number as the key factors that may lead to replace 400V with 690 V and so allowed to define general criteria that may be used for any specific installation. The most common voltage used in European industrial installations to feed LV electrical distribution network is 400 V.

Can LV cables be used in a 690 V motor?

LV cables, rated 0.6/1 kV, can be used either for 400 V or 690 V without affecting insulation withstand. With respect to cable “ampacity”, the use of 690 V motors, involving a lower load currents than 400 V, makes possible to reduce both cable conductor cross section (keeping the same voltage drop in both cases) and cable power losses.

What voltage is used to supply LV electrical distribution system?

The most common voltage used in European industrial plants to supply the LV electrical distribution system is 400 V. This level is largely used because is the same voltage level used for the public electrical distribution network, so that equipment, apparatus and components are easily available on the market.
