Monitoring high-voltage transformers and switchgear
KEMA’s monitoring activities include the physical and chemical analysis of transformer oil. Periodic checks are vital if transformers and other types of electrical switchgear are to be kept running and faults avoided. In this context, a number of analytical tests should be carried out on transformer oil at regular intervals. The findings provide insight into the quality of the oil and the condition of the system.
Insulation oil in high-voltage transformers and switchgear should be analyzed in order to determine the value of the following parameters:- appearance: color and solid contaminants
- breakdown voltage
- water content
- acidity or neutralization value
- dielectric losses / specific resistance
- interfacial tension
- gas in oil
- PCB's
- furans
- analysis frequency
KEMA has well-equipped laboratories in which numerous transformer oils are analyzed on a daily basis. The laboratory is STERLAB-certified and as such accredited by the Accreditation Council.
