As the flywheel stores energy, it speeds up, and when it discharges, it slows down to release the stored energy. To make this happen, a motor-generator (MG) unit drives the rotating flywheel, converting electrical energy to mechanical energy, and vice versa. They''re connected in a way that controlling the MG also controls the flywheel''s

6 FAQs about [Switch to release stored energy]

How is stored energy released?

Stored energy release can be done by following established procedures, using appropriate tools, or performing a system test to ensure all stored energy has been released. Once stored energy has been released, verifying that all energy sources are effectively isolated is necessary.

What is stored energy release and verification?

Stored Energy Release and Verification is the fifth step in the LOTO safety and procedures. It involves identifying and releasing stored energy and verifying that the energy sources are effectively isolated. This step is divided into three sub-points: Some energy sources, such as capacitors or springs, may store energy even after being isolated.

What is stored energy?

Stored energy (also residual or potential energy) is energy that resides or remains in the power supply system. When stored energy is released in an uncontrolled manner, individuals may be crushed or struck by objects, moving machinery, equipment or other items. How does it work? Stored energy is energy in the system which is not being used.

Can a machine/equipment reaccumulate stored energy after shutdown?

The machine/equipment has no potential for stored energy or reaccumulation of stored energy after shutdown, which would endanger employees. The machine/equipment has a single energy source that can be readily identified and isolated. Isolation and locking out the energy source will completely deenergize the machine/equipment.

Do on/off and stop buttons qualify as energy-isolating devices?

ON/OFF and STOP buttons do not qualify as energy-isolating devices. This step prevents manipulation of equipment or accidental startup. It’s accomplished in two steps: Lockout and Tagout. A lockout tagout device (e.g., breaker or ball valve lockout) holds the energy isolating device in a SAFE / OFF position.

What is stored energy and Loto?

Lockout/Tagout (LOTO) is used on stored energy sources to ensure the energy is not unexpectedly released. Stored energy (also residual or potential energy) is energy that resides or remains in the power supply system.
