Relay protection zero-drift accuracy requirements
Depending on the critical nature of the application, this accuracy requirement can be anywhere from 1% to 0. Good and reliable selectivity of the protection is essential in order to limit the supply interruption to the smallest area possible and to give a clear indication of the faulted part of the network. This makes it possi-ble to direct the corrective action to the faulty part of the network and the. These elements are crucial in determining the accuracy of fault detection and the overall performance of protection systems. Five-, ten-, and fifteen-minute outage pickup faster operation at high currents to as much as 70-cycles faster at lower currents. ers closer to the substation or use automatic sectionalizing. The invention provides a dynamic zero drift filtering algorithm for relay protection, which comprises the following steps: (1), inputting a sampling passage into a short circuit, so as to measure an initial zero drift value which is then solidified into a memorizer of the protection device; (2).

Paraguay bit error rate ±0 05dB accuracy
In, the number of bit errors is the number of received of a over a that have been altered due to,, or errors. The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. Bit er.
