5.3 Operating the Pressure Release Valve ●
If a transformer is faulty, a large amount of gas is generated, and the pressure of the insulation oil increases sharply. When the certain threshold is reached, the transformer oil is discharged and the internal pressure of the transformer decreases to a normal value. At the same time, a signal is sent to trip the circuit breaker in the ring main unit.
●
The pressure release valve can be operated in two ways. Choose one depending on the situation. Figure 5-11 Installation position of the pressure release valve

Step 3 Paint zinc-rich primer on the damaged coat using a brush or painting gun.
NOTICE
● If the base material is exposed in the area to be repaired, apply epoxy zinc-rich primer, wait until the paint has dried, and then apply acrylic acid top coating. ● Select epoxy zinc-rich primer or acrylic acid top coating with a color the same as the surface coating color of the equipment. Step 4 Apply paint evenly to the damaged area based on the damage degree of the paint using a spray bottle, brush, or painting gun until all damage traces are invisible.

Step 5 Wait for 30 minutes and check whether the painting meets the requirements. NOTE ● The color of the repainted area must be consistent with that of the surrounding area. Use a colorimeter to measure the color difference (ΔE), which should be less than or equal to 3. If a colorimeter is unavailable, ensure that there is no visible edge between the repainted area and the surrounding area. The paint should also be free of bulges, scratches, flaking, or cracks. ● If you choose to spray paint, it is recommended that you spray paint three times before checking the result. If the color does not meet the requirements, paint more times until the painting meets the requirements.
