PS-E—Provisional specifications for approval of electronic voltage transformers Category: Life is a tragedy when seen in close-up, but a comedy in long-shot. All operating, metering constants and algorithms shall not be modified or altered by any external device, communication signal, power outage or any other means which does not require breaking the device’s physical seal.
An EIT in which the secondary voltage in normal conditions of use is substantially proportional to the primary voltage and differs in phase from it by a known angle for an appropriate direction of the connections. The basic operating constant and the algorithm used in processing the measured quantities shall be stored within the EVT in such manner that they cannot be altered without breaking the device’s physical seal clause Strive not to be a success, but rather to be of value.
