5 .1 .2 Current Shunt
A shunt is used to measure the current to the terminal block. The voltage drop across the shunt
is proportional to the current flowing through it. The current shunt rating corresponds to the
ampere scale on the meter.
5 .1 .3 Adjustments
A 0 to 1 ohm, 300 Watt variable resistor located inside the cabinet may be used to adjust the
output power of the CP interface. This resistor may be connected in series or parallel with the
TEG. See Figure 28 for series connection and Figure 29 for parallel Connections.
5 .1 .4 Series
By connecting the 300 Watt resistor in series with the TEG the maximum allowable power may
be delivered to the CP load. This is achieved by moving the tap to the bottom of the resistor.
5 .1 .5 Parallel
By connecting the 300 Watt resistor in parallel with the TEG smaller levels of power may be
delivered to the CP load. This may be required when hot spots occur on the anode. With the
tap located at the top of the resistor the output power will be zero. As the tap is moved down,
the power to the CP load is increased.
