I work for a company with a High Voltage installation, it is a high voltage transformer used in the testing of certain equipment. We currently pay an external company to be the responsible 'driftsleder' for the operation of this installation. However I am a qualified Low Voltage Electrician with a 'Fagbrev' in Norway and I have undertaken the FSE safety course in Low and High voltage installations, and I am wondering what further training I would need to undertake to become the responsible 'driftsleder' for this High Voltage installation? Thank you

Dear all. Do anyone know where I can find the regulations regarding what voltage an ETR III/7 certified electrician rating can work on, on ships. From what I assume, they can work on low voltage system under 1000V..

Heisann,

Sliter med å bli 100% trygg på oversettelsen til de norske ekvivalentene til disse engelske begrepene. Noen som kan hjelpe å gi meg fasiten på dette?

(Ik)Steady-state short-circuit current:

(Ip) Maximum current (first peak of the fault current):
(Ith) Thermal short-circuit current (1s):
(zk) Short-circuit impedance:

Hi

We have a cable 3x646AWG+3x4AWG. The line conductor is approximately 330 mm2 and the protective conductors are approximately 3x21,1mm2=63,3mm2.

According to IEC 60364-5-54 table 54.2 the protective conductors have to be half the size of the line conductor multiplied with a constant a: S*a/2. Is there any other rules or regulations to consider?

Can you say something about this constant a for this cable? Can we use this cable? Is the size of the protective conductors big enough?

Can this cable be used to supply a VFD controlled AC motor? Rated Voltage: 587 V, rated current: 1120 A.
