Operatorul de distribuție restabilește curentul electric.

In Romanian, the definite article is usually attached to the end of the noun instead of appearing as a separate word like English the.

• operator = operator
• operatorul = the operator

The ending -ul is a common masculine singular definite article.
The same thing happens in curentul:

• curent = current / power
• curentul = the current / the power

So Romanian often expresses the as a suffix, not a separate word.

de is very often used to link two nouns, especially when English would use a noun before another noun.

So:

• operator de distribuție literally means something like operator of distribution
• but in natural English that becomes distribution operator

This is a very common Romanian structure. Compare:

• companie de asigurări = insurance company
• rețea de transport = transport network

In this sentence, de distribuție describes what kind of operator it is.

Because after de in this kind of label or classifier phrase, Romanian normally uses the plain noun form, not the genitive form.

So:

• operator de distribuție = the normal way to say distribution operator
• operatorul distribuției would sound more like the operator of the distribution, referring to a particular distribution process or system in a more literal way

In other words, de distribuție is the standard, idiomatic structure here.

restabilește is the 3rd person singular present tense of the verb a restabili, meaning to restore / to re-establish.

A few forms are:

• eu restabilesc = I restore
• tu restabilești = you restore
• el/ea restabilește = he/she/it restores

Here the subject is operatorul de distribuție, which is singular, so restabilește is the correct form.

In Romanian, adjectives usually come after the noun.

So:

• curent electric = electric current / electric power
• curentul electric = the electric current / the electric power

That is the normal order. English usually puts the adjective before the noun, but Romanian usually puts it after.

Romanian can place adjectives before the noun too, but that is often more stylistic, emphatic, or less neutral. In this sentence, curentul electric is the standard order.

Because electric has to agree with curentul, and curent is masculine singular.

So the adjective is also masculine singular:

• curent electric
• curentul electric

If the noun were feminine, the adjective would change:

• energie electrică = electric energy
• energia electrică = the electric energy

So this is just normal adjective agreement.

It can mean both, depending on context.

In everyday Romanian, curent or curent electric often means electricity / electric power, especially in situations involving outages and service restoration.

So in a utility context like this sentence, it usually means something closer to:

• the power
• the electricity supply

not necessarily electric current in a physics-class sense.

Because pe is not used with every direct object in Romanian.

It is commonly used with:

• people
• animate beings
• personal names
• pronouns
• certain highly specific direct objects

But curentul electric is an inanimate thing, so Romanian normally leaves out pe here.

For comparison:

• Operatorul îl anunță pe client. = The operator informs the client.

There, pe appears because clientul is a person.

The order here is the most neutral and standard one:

• Subject + Verb + Object
• Operatorul de distribuție
  • restabilește
    • curentul electric

Romanian does allow more flexibility than English, but different word orders usually add emphasis, contrast, or a special discourse effect.

So for a plain factual statement, this sentence is in the most natural order.

The two most important ones here are:

• ș = sh as in ship
• ț = ts as in cats

So:

• restabilește has ș: the end sounds roughly like -shtə / -shte
• distribuție has ț: that part sounds roughly like -tsee-eh

These letters are very important in Romanian, because changing them can change the word.

Because the sentence refers to specific, identifiable things:

• operatorul de distribuție = the distribution operator
• curentul electric = the electric power / electricity supply

Romanian, like English, uses definiteness when the speaker has a specific referent in mind. In a sentence about restoring service, both the operator and the electricity are understood as specific, so the definite forms are natural.

If you removed the definite articles, the sentence would sound much less natural in ordinary usage.
