Electrical safety in public swimming pools

With the first sunny days, many people look forward to visiting swimming pools. But what happens when it is time for periodic inspection of the electrical system? Then the swimming pool has to be closed and visitors are often left disappointed.

Is that really necessary? No! In this article, you will learn how to easily inspect the electrical installations in a swimming pool without having to close the pool and without endangering the safety of the pool guests.

No inspection without closure

As with any business, a swimming pool must be periodically inspected according to DGUV regulation 3. From hairdryers to heating for the sauna and underwater lighting. Everything has to be carefully checked. Especially because electricity and water do not form a good combination. However, periodic inspection can be more or less time-consuming, as all electrical devices and systems have to be disconnected from the mains. In larger swimming pools, the inspection may well take longer than a day. It is not possible to swim during this time. The swimming pool must remain closed.

This is frustrating, not only for the pool visitors but also for the operator. Because as a result, they lose revenue. In times when many swimming pools are economically difficult to operate, closures must be avoided as much as possible.

Safety thanks to constant monitoring

But how can this be done without endangering the safety of the pool guests? The solution: continuous monitoring with Bender's intelligent residual current technology (How does residual current monitoring work?). According to the latest version of DIN VDE 0105-100 from 2017, measuring the insulation resistance, as required in the periodic inspection according to DGUV regulation 3, can be dispensed with if an electrical system is constantly monitored by a residual current monitoring device according to DIN EN 62020 (VDE 0663) or an insulation monitoring device according to DIN EN 61557-8 (VDE 0413-8) and the monitoring device functions properly.

The 4 advantages of residual current monitoring in swimming pools

There are great reasons to equip swimming pools with residual current devices. The most important reasons are:

  • Electrical equipment and devices are constantly monitored.
  • The inspection according to DGUV regulation 3 is simplified.
  • This increases profitability because closures can be avoided.
  • This also increases safety for operators and visitors.
No more closures

These advantages convinced Bäderland Hamburg GmbH to use residual current monitoring in its swimming pools. Now the pools no longer have to be closed during periodic inspection according to DGUV regulation 3. Nevertheless, there is no safety risk to operators and pool guests. On the contrary! Safety has even increased.

So far, Bäderland GmbH has retrofitted two of its 28 pools with residual current monitoring technology from Bender. More are to follow in the next few years (read the full story here).

And your swimming pool?

There are more than 6,000 swimming pools in Germany. Each of these pools must be operated economically. The cost pressure is often enormous, especially for public pools, because many municipalities need to save money. Retrofitting electrical systems with residual current technology is therefore worthwhile. And the swimming pool guests also benefit from it.
