HMI, and download a configuration to the IED in order to make commissioning. Oct 4, Identifying the function to test in the technical reference manual If there are several out-of-step relays in the power system, then the one After each test it is possible to download and study the related.
The communications path between the relays is tested using suitable equipment to ensure that the path is complete and that the received signal strength is within specification.
Numerical relays may be fitted with loopback test facilities that enable either part of or the entire communications link to be tested from one end.
After completion of these tests, it is usual to enter the relay settings required. This can be done manually via the relay front panel controls, or using a portable PC and suitable software. Whichever, method is used, a check by a second person that the correct settings have been used is desirable, and the settings recorded. Programmable scheme logic that is required is also entered at this stage.
The ammeter connected to the secondary of the current transformer should be a robust moving coil, permanent magnet, centre-zero type. A low voltage battery is used, via a single-pole push-button switch, to energise the primary winding. This can be done by energising the secondary winding from the local mains supply through a variable auto-transformer while the primary circuit remains open. See Figure 2.
The characteristic is measured at suitable intervals of applied voltage, until the magnetising current is seen to rise very rapidly for a small increase in voltage. This indicates the approximate knee-point or saturation flux level of the current transformer. The magnetising current should then be recorded at similar voltage intervals as it is reduced to zero.
The short-time current rating must be in excess of the CT secondary current rating, to allow for measurement of the saturation current. The main application is rough testing of relays in the laboratory or the field.
