CPC G01R 31/3274 (2013.01) | 10 Claims |
1. A contact measurement system for measuring a parameter of a contact of a switchgear, comprising:
a first device configured to measure an electrical resistance of the contact and to map the electrical resistance spatially and/or dynamically;
a second device configured to measure an axial force of the contact and to map the axial force spatially and/or dynamically as a measured axial force; and
a third device configured to measure a position of the contact,
wherein the contact measurement system is configured to determine a position-depending force characteristic based on the measured axial force of the contact and the position of the contact,
wherein the contact measurement system is configured to determine a status of the contact based on a combination of the position-depending force characteristic with the electrical resistance of the contact using position-dependent resistance measurements and contact force measurement,
wherein the first device configured to measure the electrical resistance comprises a 4-point measurement setup, and
wherein the third device configured to measure the position of the contact is configured to be switched-off in a suspend mode,
wherein the contact measurement system is configured to determine a force characteristic based on the measured axial force of the contact, and
wherein the contact measurement system is configured to determine a status of the contact based on a combination of force characteristic with the electrical resistance of the contact.
