IEEE C62.36-1991 pdf download.IEEE Standard Test Methods for Surge Protectors Used in Low-Voltage Data, Communications, and Signaling Circuits.
Abstract:Methods for testing and measuring the characteristics of surge protectors used in low voltage data, communications, and signaling circuits with voltages less than or equal to 1000 V rms or 1200 V dc are established. The surge protectors are designed to limit voltage surges, current surges, or both. The surge protectors covered are multiple-component series or parallel combinations of linear or nonlinear elements. Tests are included for characterizing standby performance, surge-limiting capabilities, and surge lifetime. Packaged single gas-tube, air-gap, varistor, or avalanche junction surge-protective devices are not covered, nor are test methods for low-voltage power circuit applications.
Keywords: communications circuits, data circuits, electrical protection, signaling circuits, surge protectors, surge-protective devices, voltage limiters.
IEEE C62.36-1991 applies to surge protectors for application on multiconductor balanced or unbalanced data, communications, and signaling circuits with voltages equal to or less than 1000 V FTflS, or 1200 V dc. These surge protect,ors are designed to limit voltage surges, current surges, or both.
IEEE C62.36-1991 describes the methods of testing and criteria for determining the end of life of electrical surge protectors used in lowvoltage data, communications, and signaling circuits. The surge protectors covered are multiple-component series or parallel combinations of linear or nonlinear elements, packaged for the purpose of limiting voltage, current, or both.
IEEE C62.36-1991 is not intended to cover packaged single gas tube, air gap, varistor or avalanche junction surge-protective devices, which are included in IEEE C62.31-1987 [2], IEEE C62.32-1981 [3], IEEE C62.33-1982 [4], and IEEE C62.35-1987 [5], respectively. Specifically excluded from this standard are test methods for low-voltage power circuit applications. For protection of wire-line communication facilities under the specialized conditions found at power stations, consult IEEE Std 487-1980 [9].
The tests in this standard are intended as design tests as defined in IEEE Std 100-1988 [7], IEEE Standard Dictionary of Electrical and Electronics Terms, and provide a means of comparison among various multiple-component surge protectors.
This section contains only those definitions relating to surge protectors, within this standard, that are not listed in IEEE Std 100-1988 [7].
surge protector. An assembly of protective devices consisting of one or more series, parallel, or any combination of elements used to limit surge voltages, currents, or both to a specified level. Syn: protector.
transition current. The current required at a given temperature and duration to cause a current-protective device to change state.IEEE C62.36-1991 pdf download.
