High Voltage Hysteresis Comparator Design
The voltage level are quite high for which I am getting confused as
  how to replicate these accurately


Yes, they are a bit high so I would divide the input voltage down to something more manageable. Maybe a 10:1 resistor divider is something like what you want to convert 57 volts to 5.7 volts. Then you are in the right sort of territory.

However, you haven't said how high the input voltage could reach but assuming the maximum input voltage was 100 volts, a 10:1 divider is still reasonable for a comparator operating from a +15 volt rail.

But you haven't said how low the input voltage could go so if it is -100 volts you'll need a +/- 15 volt supply rail for you comparator.

You haven't specified accuracy i.e. it should switch positive for a voltage between 56 volts and 58 volts, so you need to consider this.

Once you have your limits and accuracy required you can start the design process proper. You can use one comparator but, if you need good and accurate independent control of both thresholds I would suggest two comparators and D type flip flop as your starting point.

One comparator triggers on the high level and one on the low level. The high-level comparator clocks "1" into the flip flop and the low-level comparator resets the flip flop.

Again, accuracy might be very important so, to generate the trigger threshold voltages you might want to use a precision voltage reference of 10 volts and potential dividers to produce upper and lower threshold voltages.

That is as much design I intend to do. The rest is for you to figure out.
