Laboratory testing of high- and medium-voltage components

As a standard service, FKH offers diagnostic insulation measurements on all high-voltage electrical equipment delivered to its own laboratory; in particular, detailed assessments based on partial discharge measurements can be provided regarding the condition of insulation on new components as well as older components that are already in operation.

For small service-aged items of high-voltage equipment such as switchgears, measuring transducers, bushings and busbars with nominal voltages of up to 50 kV, a high-voltage test with partial discharge measurement in the laboratory can be more efficient than an on-site measurement. FKH has a shielded high-voltage laboratory that can handle surge voltages and AC test voltages of up to approx. 150 kV. As required, FKH will clarify which approach is more favourable and economical (on-site testing or laboratory testing).
