Standard TEG Constant Temperature Characterisation. This test involves applying a fixed temperature difference across the TEG starting at open circuit voltage, performing a load sweep to short circuit current. Because the TEG heat flux changes with each electrical load point, our test system adjusts heater power and chiller power to maintain the same fixed temperature difference across the TEG. The result is a I-V/I-P (Current/Voltage, Current/Power) graph and associated values of temperature, voltage and current at each load point. The system measures hot side, cold side, water in/water out temperatures; all electrical parameters (voltage/current/power); flow meter readings, heater input power (and voltage and current). We also clamp the module up to your required pressure. For standard TEG modules, this is usually 1.25MPa. The test results will also provide a measurement for this applied pressure. The heater unit is insulated so the power to the heater is the heat flux through the module. We measure the heater power. We offer this at £150 per test.
