Abstract
A monitoring method for an electrical energy transfer device which has a first phase conductor and a second phase conductor, includes the following steps: a temperature of the first phase conductor is compared with the temperature of the second phase conductor and a signaling is performed if there is a deviation between the temperatures. The electrical energy transfer device is, for this purpose, equipped at the first phase conductor with a first temperature sensor and at the second phase conductor with a second temperature sensor.
Claims10
A monitoring method for an electric power transmission device having a first phase conductor and a second phase conductor, the monitoring method comprising:
- acquiring a temperature of the first phase conductor and a temperature of the second phase conductor;
- comparing the temperature of the first phase conductor with the temperature of the second phase conductor;
- if there is a difference between the temperatures of the first and second phase conductors, performing a signaling;
- and
- producing a forecast for a characteristic of a temperature load on at least one of the phase conductors from ascertained measured values.
An electric power transmission device, comprising:
- a first phase conductor and a second phase conductor;
- a first current measuring device for said first phase conductor and a second current measuring device for said second phase conductor;
- said first phase conductor having a first temperature sensor and said second phase conductor having a second temperature sensor;
- and
- said first temperature sensor being configured to acquire a temperature of said first phase conductor and said second temperature sensor being configured to acquire a temperature of said second phase conductor, and wherein the temperature of the first phase conductor is compared with the temperature of the second phase conductor, a signaling is performed if there is a difference between the temperatures of the first and second phase conductors, and a forecast is produced for a characteristic of a temperature load on at least one of the phase conductors from ascertained measured values.
