Hi Andrew, 

MOV -- Metal Oxide Varistor - A variable resistor used to protect 
circuitry against overvoltage surges, resistance stays very high until 
the cut-off voltage is reached then quickly decreases to almost 
zero, thus effectively shorting out the over voltage until it drops 
back down to safe levels. 

KV -- kilo-volts or 1000 volts 
KVA -- Kilo-volt-amps or 1000 volt/amps example: 100 volts -at- 10 
          amps equals 1000 volt/amps 

1350 RPM with 8 rotary electrodes should yield approximately 
180 bps. This would not run synch from 60 hz mains freq, but 
this is a reasonable bps rate. Synchronous bps rates at 60 
hz would either be 120 bps or 240 bps.
