4.6.1 Transformer Testing Suggestion

Transformer Testing Suggestion

Figure 32 shows an example relay. Inspect the isolation valve to ensure it is open. With the transformer offline and under clearance, functionally test the sudden pressure relay by slowly closing the isolating valve. Leave it closed for a few seconds and reopen the valve very suddenly; this should activate the alarm. If the alarm does not activate, test the relay. If the relay fails to function, replace it with a new one.
