BTW- these regs stink. I have been swapping them with Basler SSRs for a few years now. A little more money, but they last a lot longer.

You need to spec digital VR, otherwise you get analog one.

i have some questions.
there're two "nuts" on AVR to adjust GAIN and VOLTAGE. i want to know how to adjust to get the right DROOD and VOLTAGE. And another question is : the system has three generators are paralleled. when the load changes, the power factors also change. how can i solve this problem?
RE: AVR FOR CAT'S GENERATOR
The power factor problem requires power factor controllers. When you set a fixed output to parallel, that is the unity var setting when the breaker closes. When you add load the excitation needs to be increased in relation to the load.
The power factor controller can be set to a var or power factor setting (you want pf). It will constantly adjust power factor as the load varies.
We have used Basler SCP-250 power factor controls with the cat regulator you describe with good results. You need access to a current transformer for this to work.
