It increases the conductivity of the water
Low conductivity is better if you don't want electricity to pass. High conductivity is better if you do want electricity to pass. Also, water itself is actually an insulator (very low conductivity) but the impurities in water can be great conductors. Pure water will stop electric flow, but it is very difficult (outside of a lab) to get truly pure water.
conductivity is not zero because water itself has ions i.e. H+ & OH- so conductivity cannot be zero. even if you use EDI still some conductivity will be left it will be almost negligible but still conductivity will be there.
Conductivity can be used to calculate the salinity of the water.
The commonest test is to check the electrical conductivity between two electrodes. Pure water has very poor conductivity, but the conductivity improves as more ions are dissolved in it. Sea water has a conductivity of around 5 S/m (Siemens per metre) Drinking water has a conductivity of 0.005 - 0.05 S/m . Ultra-pure water has a much lower conductivity of 5.5 x 10-6 S/m - a million times smaller than that of sea water.

It increases the conductivity of the water
Purpose of maintaining conductivity of primary water in a generator is 1. To avoid earth fault caused by excess conductivity. 2. To avoid corroision of primary water system (including stator windings) as water gets acidic with low conductivity(due to ion exchanger used for reduction of conductivity). P.S. conductivity of PW for a 500 MW generator is usually maintained b/w 1 to 2 micro S/cm.
Pure water has extremely low conductivity but any dissolved salts in the water increase its conductivity. Sea water with 3% salt has a high conductivity of 5 S/m.
A PH meter measures conductivity to tell the amount of Hydrogen in a solution. A conductivity meter is used to measure the purity of water in ohms. A battery is a great example of solution conductivity at work.
Unit of dm water conductivity is microsiemens/cm
