Abstract

Disclosed is a method comprising discharging electrical energy from an intermediate circuit comprised in the apparatus; measuring a direct current voltage; inputting measured values to a parameter estimator for the intermediate circuit, wherein the parameter estimator comprises at least a first parameter and a second parameter whose values are determined based on an equivalent capacitance value of the intermediate circuit, an equivalent resistance value of the intermediate circuit and an electrical load power value of the intermediate circuit, the parameter estimator outputting values for time constant and values for power-to-capacitance ratio of the intermediate circuit; and storing values at least temporarily for condition monitoring.
