Page 12: Introduction
INTRODUCTION Since the enactment of the National Energy Act of 1979 a large number of small private energy producers have been planning and building small generation facilities in order to sell power to the local utili ty_ Electric utilities across country have been plaruling for intercormection of these small generators, have been working on solutions to the associated problems that interconnection creates.
Page 13: Application
However, the flexibility of the PRIDE has been increased as additional features were added. The M-0290 can now be used in a variety of applications where a multi-function voltsge and frequency relay is needed.
Page 14: Operating Principles
OPERATING PRINCIPLES In order to understand the operation of the microprocessor-based relay, refer to the Functional Diagram shown in Figure This diagram indicates the mix of hardware software and represents the software in a logical form, but does not represent the actual mechanization of the relays or the flow of the program.

Page 17: Frequency Measurement Time Curve
Time Delay (fran Figure 2) = 0 . 19 sec (ll.4 cycles) FREQUENCY MEASUREMENT TIME The time required for the M-0290 to detect an over or under frequency eondi tion is dependent on the frequency before and after an input frequency step change and the setpcint for the OVer/Under Frequency detector.

Most utilities have standardized on one of many different test blocks, Westinghouse and States being the most common. 'fuerefore, Beckwith Electric has not suWlied a test block on the PRIDE Unit, thus enabling the user to incorporate his standard test block. This must be added external to the PRIDE Unit.
