METHOD AND DEVICE FOR DETERMINING QUALITY OF VOLTAGE AND / OR CURRENT POWER SUPPLY DEVICE

摘要

1. A method for determining the quality of voltage (U) and / or current of a power supply device, in which voltage parameters (U, f, H3, H5, GHV) and / or current are continuously recorded and the quality of voltage and / or current, which differs from the registered parameters, is determined by registering deliberately shutdowns (A) of the power supply device, and during the duration of shutdowns, the registered parameters (U, f, H3, H5, GHV) are marked in a special way. 2. A method according to claim 1, characterized in that the power supply device with the disconnector (3) deliberately shutdowns (A) are recorded by recognizing the position of the disconnector (3). 3. The method according to claim 2, characterized in that the duration of deliberately shutdowns (A) is obtained from the time between the initial moment of time (t) and the final moment of time (t), and the initial moment of time (t) is the instant of opening of the disconnector (3) minus the interval (a) of the tolerance time, and in this case, the final moment of time (t) is the instant of closure of the disconnector (3) plus the interval (a) of the tolerance time. 4. The method according to claim 1, characterized in that in order to recognize deliberately shutdowns (A), violations of the limit values of the voltage (U) and / or current of the power supply device are recorded, and when the violation of the limit value exceeds a predetermined time duration, the registered parameters (U, f, H3, H5, GHV) are marked in a special way. 5. The method according to p. 2, characterized in that for the recognition of deliberate shutdowns (A), violations of the limit values of the voltage (U) and / or current of the power supply device are recorded, and when the violation of the limit value exceeds a predetermined duration
