1. A method for collecting data related to a status of an electrical power system operatively coupled with a microprocessor-based relay, comprising:
- acquiring data from said electrical power system;
storing at least temporarily the acquired data in a first volatile memory;
upon the occurrence of an event, copying the data stored in said first volatile memory and permanently storing the copied data in a second non-volatile memory; and
after the cessation of the event, verifying if the data copied from said first volatile memory has been correctly stored in said second non-volatile memory.

Abstract
A method and an apparatus for collecting data related to a status of an electrical power system, wherein data is continuously acquired from the electrical power system and is stored, at least temporarily, in a first volatile memory. Upon the occurrence of an event, the data stored in the first volatile memory is copied and permanently stored in a second non-volatile memory.
