Coordination of Insulation

Transactions of the American Institute of Electrical Engineers, 1933
The general scheme of coordination is discussed. Average circuit insulation used in 1930 is shown. The relation that switching surges and arcing ground overvoltages bear on coordination is discussed giving the number and magnitude of such waves found in service.

Insulation Coordination for Gas Insulated Substations

IEEE Transactions on Power Apparatus and Systems, 1973
This paper presents the development of BIL (Basic Lightning Impulse Insulation Level) ratings for SF6 gas insulated substations from 72.5 kV to 765 kV. The unique properties of the gas insulated substation are analyzed and insulation coordination design techniques are utilized to determine BIL ratings for the substation equipment, other than the ...

Insulation coordination of distribution transformers

Electrical Engineering, 1932
In this study of insulation coordination of distribution transformers, the operating conditions are reviewed and the requirements of transformers to be operated without protection are outlined. Test results on transformers designed to meet these requirements are given, showing that by the use of shields for the high-voltage windings and thyrite ...

765-kV Station Insulation Coordination

IEEE Transactions on Power Apparatus and Systems, 1969
Specially designed arresters are used in the American Electric Power 765-kV station insulation coordination as a first line of defense against overvoltage. The arresters have the ability to withstand sustained and dynamic overvoltages in excess of their rating. They also have the ability to discharge repetitively.

Insulation Coordination for 38 kV Circuit Breakers

IEEE Power Engineering Review, 1985
Based on a review of the impulse insulation requirements for 38 kV circuit breakers and the impact of insulation coordination using modern arresters, a change is suggested in the way the impulse requirements are stated for the circuit breaker. The facets of circuit breaker design which may be affected are indicated. Specifically it is suggested that in

Turn Insulation Capability of Large AC Motors Part 3 - Insulation Coordination

IEEE Transactions on Energy Conversion, 1987
The coordination of the surge strength of large AC motor stator windings with the surge voltages encountered during normal switching of the motors in utility generating stations is described in this paper. The surge strength of the turn insulation of motor windings was determined from destructive tests on 17 stators [6].

Lightning Insulation Coordination for a ??600-kV DC Gas Insulated Cable

IEEE Power Engineering Review, 1982
To determine the required BIL of a +600 kV dc gas-insulated cable, a probabilistic insulation coordination study was performed. An equation was developed to determine the maximum voltage on the cable as a function of directly connected highly nonlinear surge protective devices (MO).
