PMG– Maintenance and Safety Tips

A Permanent Magnet Generator (PMG) is an electrical machine that converts mechanical energy into electrical energy.

Carrying out certain maintenance procedures and functions can be dangerous or even fatal if correct safety precautions are not observed;

– Pre-Function Precaution

Before attempting to set up, adjust or operate synchronous machines, operators and must have technical qualification or have received appropriate related training. Personnel must thoroughly go through PMGL’s ‘User’s Manual’ on safety instructions, and follow them.

– Sense of Symbols & Decals

It is required for the user to be familiar with all the warning symbols and decals of the machinery.
Failure to observe a warning sign or read the associated safety information may cause physical injury or death.

– Escape high temperatures

PMGs are able to reach high temperatures. Users must avoid any direct contact with them. Protective gloves must be used by individuals working in vicinity of the machines.

– Protection from Moving parts

Covers removed as part of maintenance, setting-up or installation process must be done by qualified people. They must then be re-fitted as soon as possible.
Keep hands and loose clothing away from all moving parts.

– Insulation to Electrical hazard

PMGs induce high voltage when there is certain rotational speed. During its installation, one must prevent touching its voltage output terminals and wires. Protective insulation is highly recommended.

– Threat of Magnetic fields

There is a magnetic field present in the immediate area around a PMG, even when it is not operating.
The devices that can be influenced or wiped by electro-magnetism (e.g. magnetic
disks, watches, credit cards,) must be removed from the area. A magnetic field can alter the effect of some medicine devices like a pacemaker. Such devices must therefore be avoided close to a PMG.
