Leisure and amusement parks

Time also leaves its mark on existing and permanently installed systems. Cable insulation becomes brittle, appliances become susceptible to failure. Environmental influences such as solar radiation, heat, cold and moisture are added to this. This reduces the insulation level of the installed cables and devices.

The poorer the insulation level, the higher the residual currents and thus the risk of electrical accidents. This risk is much higher for water attractions and rides.

To prevent electrical accidents, measures must be taken to recognise fault currents before they can become dangerous for people.

Residual current monitoring systems from Bender detect fault currents before they can become dangerous for people. This prevents accidents caused by electric shock.

Operators can set a threshold value for residual currents that is safe for humans (e.g. 30 mA). If this value is exceeded, an alarm is triggered. This gives operators the opportunity to react immediately, rectify the fault in the system and thus prevent electrical accidents.

For operators this means:

•  Fast and safe residual current detection
•  Avoidance of dangerous situations
•  Prevention of electrical accidents

According to DIN VDE 0105-100 and DGUV Regulation 3, the safety of every electrical system must be checked regularly. This test serves to protect the system and persons and is intended to prevent electrical accidents or dangerous situations when handling electrical current.

However, carrying out the recurrent tests takes a lot of time. The more complex the electrical system, the longer the test takes. In particular, the prescribed measurement of the insulation resistance (Riso) is very time-consuming, because not only does the entire power supply have to be switched off, but cables and devices also have to be disconnected. Errors can also occur when reconnecting cables and devices.

Theme park and amusement park operators have an interest in ensuring that their rides and attractions are available and not cancelled for days on end. A solution is therefore required that reduces the time and effort required for recurrent testing without jeopardising the safety of the systems and neglecting personal protection.

With a Bender residual current monitoring system, operators of amusement parks, rides and attractions can dispense with time-consuming Riso measurements. This measure also addresses the shortage of skilled labour, as fewer staff are needed for the repeat examinations.

A residual current monitoring system also increases safety for the system and people. This is because instead of testing every four years, the insulation resistance is measured continuously. Faults in cables or devices are thus recognised at an early stage and dangerous situations are avoided.

Bender POWERSCOUT® is available for storing, visualising and documenting the measured values. The POWERSCOUT® measurement logs are also used to document the DGUV Regulation 3 tests.

Benefits for operators:

•  Less time and manpower required for Riso assessment
•  Higher availability of attractions/rides
•  More safety for people and systems thanks to permanent measurement instead of snapshots

Note:

The residual current monitoring system from Bender can be integrated into existing technology.
