Liquid Resistant Starter for 4.8 mW Slip Ring Motor

What is the electrolyte medium saline or caustic?

1.38 is the norm for caustic.

4.8 milliwatt?

Here is an excerpt form wikipedia:

The electrolyte is normally a custom solution of sodium carbonate (soda ash) mixed on-site for the specific job.
This salt is alkaline and electrode corrosion effects on galvanised steel tanks is manageable if re-galvanisation is possible.
The resistance of the bulk electrolyte is a function of temperature and the concentration of the salt[2] governed by the formula:
Rθ = R0 /(1 + 0.03θ )
where θ is the temperature (in Celsius) and R0 is the standardised or datum calibration temperature.

A specialised technique is required to accurately calibrate an LNER electrolyte bulk resistance value and it is normally carried out by experienced power engineers and technicians. This task must be done off-load at routine intervals (roughly 2-4 years depending on results from routine monitoring) to maintain the resistance value within tolerance and facilitate inspection of the LNER.

Hope this helps.

Do you have access to the manual for the 4,800,000W motor starter or is this a homework question?
