Test Results: Title: Measurement Fault Calculator

1. The document reports the results of tests on an electrical protection relay, including measurement of currents, overcurrent and earth fault element settings, shot test configurations and results, and characteristic curves. 2. Shot tests were conducted on the relay at various current levels and phase angles to test the operation of the overcurrent and earth fault elements. All tests resulted in the element operating within accepted time deviations and the relay passing the tests. 3. Characteristic curves are presented for the various protection elements showing the operating times across a range of fault currents, consistent with the set inverse and definite time trip characteristics.
