Extraction of thermal time constant in HBTs usingsmallsignal measurements

open access: yesElectronics Letters, 1997
A novel method for finding the thermal time constant of HBTs is proposed. It utilises small signal measurements in the frequency domain of the typical negative differential resistance found in the active region, i.e. normal bias conditions for the device.

Lifetime Assessment of PILC Cables with Regard to Thermal Aging Based on a Medium Voltage Distribution Network Benchmark and Representative Load Scenarios in the Course of the Expansion of Distributed Energy Resources

open access: yesEnergies, 2021
The decentralized feed-ins from distributed energy resources (DER) represent a significant change in the manner in which the power grid is used. If this leads to high loads on electrical equipment, its aging can be accelerated. This applies in particular

The thermal inertia time constants and its influencing factors in the thermal dynamic process of overhead line and cable [PDF]

open access: yesE3S Web of Conferences, 2020
Due to the existence of thermal capacity, the conductor temperature of overhead line and cable changes later than current steps (thermal inertia), and the thermal dynamic process of the conductor contains the huge current-carrying potential.

Determination of the thermal time constant of the reinforced concrete building component [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2017
As a result of changes in the boundary conditions, a heat exchange in the building envelope is not always in a steady state. Heat fluxes penetrating through the wall may be several times greater than the steady state.
