摘要：The article aims to present the issue of excessive heat release at
installation joints due to insufficient contact surface of the joining
elements. The conducted research attempts to estimate the losses caused by
an insufficient contact surface area. A laser pyrometer and a thermal
imaging camera were used to perform the tests. Both devices generate
images without having to touch the tested element, which may indicate that
the obtained results are very accurate. The completed tests have shown that
an insufficient contact surface of the joints results in an increased heat
release, which leads to higher electrical energy losses and increased wear
of the installation connectors.
