6 FAQs about [Maintenance of battery packs in transformer substations]

Why are batteries important in a substation?

Batteries are among the least expensive pieces of equipment in a substation, and they are the heart that keeps the protection and control system running. Despite this, they are often not maintained properly. NERC standards make battery maintenance mandatory and its requirements are more stringent than those for other equipment.

What types of batteries are used in distribution substations?

The types of batteries used in distribution substations are as follows. 2. 3. 4. 2. 3. 4. 5. 6. 7. 8. 9. 5. Nickel–cadmium VRLA 6. NB: VRLA (valve regulated lead–acid) batteries.

How many volts a battery should a substation have?

Those batteries usually have a rating of 45 Ah (min), 24 V to meet the load requirement of the substation. Table 4.9 gives the cell voltage of different voltage level batteries and Table 4.10 compares the different types of batteries.

Why is a DC supply used in a substation?

To avoid any such situation, a DC supply is used . The DC supply is provided by the batteries and the charger is used to keep the batteries healthy by charging the batteries in oat/boost mode as required. In a substation, the battery is commonly used to power the supply relay and breaker tripping mechanism.

Why is maintenance important in a substation?

Maintenance is a key part of lifecycle asset management. Preserving equipment health maximizes the efficiency and cost-effectiveness of substation assets, including transformers, circuit breakers, protection equipment, CTs, PTs, CCVTs, batteries, transmission lines, and more.

How to maintain a reliable battery power supply?

These monitoring device operations are ensured by a trustworthy battery power supply, leading to successful operation of that device. Thus it is essential to maintain a reliable battery power supply by proper inspection for proper operation of the monitoring device.
