IEEE 62.2-2004 pdf download IEEE Guide for Diagnostic Field Testing of Electric Power Apparatus— Electrical Machinery
1.1 Scope
This guide describes off-line inspections and diagnostic tests which are performed in the field on rotating electrical equipment with voltage ratings of 4000 V or greater. The guide is intended to address large industrial and utility sized machinery. These evaluation procedures, which are in common use on large rotating machines, have been found prudent in assuring high equipment reliability at low overall maintenance cost. The procedures are presented in categories depending on the subsystem of the machine being examined.
Purpose
This guide is intended to assist maintenance personnel in determining what diagnostic tests should be plannedfor their rotating electrical machines, what should be expected of the tests, and in general, how to perform thetests. This guide brings together, into one document, many commonly-performed appropriate tests forelectrical machines. and references other individual standards so more detailed information may be obtained

3. Definitions
For the purposes of this document, the following terms and definitions apply. The Authoritative DictionaryofIEEE Standards Terms should be referenced for terms not defined in this clause.
3.1 apparent charge (terminal charge): That charge that, if it could be injected instantaneously betweenthe terminals of the test object, would momentarily change the voltage between its terminals by the sameamount as the partial discharge itself. The apparent charge should not be confused with the chargctransferred across the discharging cavity in the dielectric medium. Apparent charge within the terms of thisdocument,is expressed in coulombs. abbreviated C. One picocoulomb (pC) is equal to 10-12 coulombs
3.2 diagnostic field tests and measurements (power apparatus): Procedures which are performed on site on the complete apparatus or parts thereof in order to determine its suitability for service.
