TEST PROCEDURE SURGE WITHSTAND CAPABILITY (SWC) FOR PROTECTIVE RELAYS AND RELAY SYSTEMS

Revision 0

01/01/2001

(1) Object This document outlines the test requirements and procedure for carrying out and documenting surge withstand capability (SWC) tests for the purpose of testing for compliance of our products with the IEEE standard C37.90.1-1989. For reasons of clarity, the product to be tested will be referred to as the "EUT" (Equipment Under Test) and "AE" as Auxiliary Equipment and "PSU" as power supply unit. (2) Reference Documents Generic Standard = IEEE C37.90-1989 Basic Standard = IEEE C37.90.1-1989 (3) Test Conditions Ambient Temperature = -20°C to 55°C measured 30cm from enclosure Relative Humidity = Outside enclosure < 55% non condensing at temp of <40deg C = Inside enclosure < 95% for 96 hr non condensing (4) Set-up Procedure for Monitoring EUT (4.1) Stimulation and Monitoring of the EUT Operation and performance of the EUT must be monitored during testing. This will be achieved by operating the module in a manner designed to exercise all functions. The test may be based upon the set-up described in the Functional Test Specification/Procedure for the EUT, as used by the test department. (4.2) Table Top Set-up Place the EUT on a 100mm stand off box at the position marked EUT and connect the primary earth point to the table top ground plane using the earth strap provided. Place the power supply on a 100mm stand off box at the position marked PSU and EMC Test Report P874-IEEE C37.90.1 Page 6 of 9

Model UC625 (P874) IEEE C37.90.1 connect the earth strap provided. Connect the PSU to the EUT with a cable length of no greater than 1 metre. Place the test generator on a 100mm stand off box at the position marked TG and connect the earth strap provided. Connect the capacitive coupler 100nF/1000V. (4.3) EUT Set-up during Surge Testing During the Surge tests, the EUT must be powered and stimulated in a mode representative of normal operation in the field. For P874 Alarm cards, this would mean the application of an input signal compatible with the input requirements. The EUT should also be tested in its most vulnerable mode, and care should be taken to ensure the most sensitive input range is tested, and also that any product with a wide-ranging specification should be tested at the sensitive part of its specification. Typically the inputs could be normally open or closed. (4.4) Monitoring EUT Behaviour during Surge Testing Any variation to the output ports of the EUT during surge testing must be recorded. This can be achieved for both display and relay ports by visually monitoring attached LED’s. However the comms is somewhat more difficult and requires the connection of a computer running a test comms program. (5) Applying Tests Refer to IEEE C37.90.1 for examples of test set-ups and background information. (5.1) Before Commencing Tests Read the operating instructions for the surge generator, especially sections relating to safety when using high voltage test-gear. The surge generator must be checked for correct operation prior to conducting the tests. THE STANDARD STATES THAT THE TEST RESULT IS A PASS WHEN NO ERRONEOUS OUTPUT IS PRESENT, NO COMPONENT FAILURE OCCURRS, AND THERE IS NO CHANGE IN CALIBRATION EXCEEDING NORMAL TOLERANCES. (5.2) Alarm ports – Common Mode – Oscillatory and Fast transient The test is applied between an alarm port and the local ground plane via the Capacitive Coupler typically 100nF/1000V, all port wires not being tested should be kept as far away as possible. Ensure that the plastic cover is always placed over the capacitive coupler before proceeding with any tests. (5.2.1) Run the test with the Surge generator set for Oscillatory mode and carefully monitor the EUT for any disturbance. Note the level of the disturbance for inclusion in the report. When the test has finished, check for correct operation of the EUT and that no configuration change or loss of function has occurred. (5.2.2) Repeat (5.2.1) above for all alarm ports and states.

Model UC625 (P874) IEEE C37.90.1 (5.2.3) Repeat (5.2.1) and (5.2.2) above with Surge generator set for Fast Transient mode. (5.3) Relay ports - Common mode – Oscillatory and Fast transient The test is applied between a relay port and the local ground plane via the Capacitive coupler typically 100nF/1000V, all port wires not being tested should be kept as far away as possible. Ensure that the plastic cover is always placed over the Capacitive coupler before proceeding with any tests. Repeat the procedure (5.2) above for all relay ports and states. (5.4) Display ports - Common mode – Oscillatory and Fast transient The test is applied between a display port and the local ground plane via the Capacitive Coupler typically 100nF/1000V, all port wires not being tested should be kept as far away as possible. Ensure that the plastic cover is always placed over the capacitive coupler before proceeding with any tests. Repeat the procedure (5.2) above for all display ports and states. (5.5) Power ports - Common mode The test is applied between a power port and the local ground plane via the Capacitive Coupler typically 100nF/1000V, all port wires not being tested should be kept as far away as possible. Ensure that the plastic cover is always placed over the capacitive coupler before proceeding with any tests. Repeat the procedure (5.2) above for all power ports and states. (5.6) Alarm ports – Transverse mode – Oscillatory and Fast transient The test is applied between two alarm inputs connected together via the capacitive coupler typically 100nF/1000V and the test generator, all port wires not being tested should be kept as far away as possible. Ensure that the plastic cover is always placed over the capacitive coupler before proceeding with any tests. (5.6.1) Run the test with the surge generator set for Oscillatory mode, and carefully monitor the EUT for any disturbance. Note the level of the disturbance for inclusion in the report. When the test has finished, check for correct operation of the EUT and that no configuration change or loss of function has occurred. (5.6.2) Repeat (5.6.1) above for all alarm port combinations and states and both polarities. (5.6.3) Repeat (5.6.1) and (5.6.2) above with Surge generator set for Fast Transient mode. (5.7) Relay ports – Transverse mode – Oscillatory and Fast transient The test is applied between two different relay ports connected together via the capacitive coupler typically 100nF/1000V and the test generator, all port wires not being tested should be kept as far away as possible. Ensure that the plastic cover is always placed over the capacitive coupler before proceeding with any tests. Repeat (5.6) above for all relay ports and states. 5.8) Display ports – Transverse mode – Oscillatory and Fast transient EMC Test Report P874-IEEE C37.90.1 Page 8 of 9
