Well, if any non-monitor is directly next to your system, then your isMonitor() function will erroneously return true for that device… this'd lead to your loop down the bottom erroring out.

It looks like you're really after peripheral.find():

local monitors = {peripheral.find("monitor")}

turbines = {peripheral.find("BigReactors-Turbine")}
monitors = {peripheral.find("monitor")}

for i=1, #monitors do
  monitors[i].clear()
  monitors[i].write("*")
end
print ("Amount of turbines found: "..table.getn(turbines).."\n")
for i = 1, #turbines do
	monitors[1].write(turbines[1].getActive())
end

turbines = { peripheral.find("BigReactors-Turbine") }

On your first line, you're missing a closing quote and closing brackets/parenthesis

turbines = { peripheral.find("BigReactors-Turbine") }

monitors[1].write(turbines[1].getActive())
--#Should be
monitors[1].write(turbines[i].getActive())

if (turbines[i] and turbines[i].getActive) then
   monitors[1].write(turbines[i].getActive())
end

At the same time, I would first make sure that such values exist.

if (turbines[i] and turbines[i].getActive) then
   monitors[1].write(turbines[i].getActive())
end

If nothing prints out then we know for a fact that you're for some reason not getting properly wrapped turbines, or that they don't have a .getActive method
