Set-up Voltage:
V
set
Voltage from the power unit for a specific ambient temperature, which
is proportional to set-up power. Fuel flow to the burner is adjusted so that proper voltage
exists, necessary temperature difference within the power unit maintained, to deliver
required power.
Open Circuit Voltage:
Voltage at the terminals of the power unit when no current is flowing,
i.e. open circuit, which is related to the temperature across the thermoelectric materials
inside the power unit.
When a power unit lead is suddenly disconnected, breaking the circuit to the load, the voltage
measured across the power unit leaps up to a new value. This is known as the momentary
open circuit voltage (V
oc
).
Measured V
set
:
V
set
measured across the precision load on the output of the electronics
without a customer load connected using a voltmeter.
Required V
set
:
V
set
needed to achieve rated power for the present ambient temperature.
CP (Cathodic Protection):
Thermoelectric generators are used in impressed current
systems for Cathodic corrosion protection of metallic structures such as pipelines.
CP Interface System:
An assembly of electrical components system that acts as an
interface between the TEG and the CP load, which also provides for adjustment and
monitoring of power to the CP load.
Converter/Limiter (C/L):
A specific electronic device attached between the generator and
the load that converts one level of DC voltage to another and limits the power unit voltage.
Manual Shutoff Valve:
A manually operated valve in the gas line for completely turning on
or shutting off the gas supply to the TEG.
Solenoid Valve (SV):
A electrically actuated valve that controls the gas supply to the
burner. This Valve is operated by the Ignition Control Module.
