Care
of Low Voltage Equipments
In order that an extra low-voltage circuit may function well all
connections must be kept clean, dry and free from corrosion.
• After sterilization, heat processed
apparatus must be dried before storing away.
• Good contact of the connections must be
maintained and loose contacts repaired immediately by the electrician when they
are detected.
• Lamps must be tightly screwed in position.
• And the current source should, if possible,
remain fairly constant. Therefore, batteries must be replaced before they are
exhausted. Batteries left too long in the metal case tend to sweat, especially
in humid atmospheres, causing corro-sion and the discharge of power. All
batteries not in actual use should be stored under dry conditions.
Rechargeable
Battery Packs
Rechargeable
nickel-cadmium batteries are being used as accessory of medical equipments.
These are expensive and have a limited life, although are electrically safe.
• Rechargeable batteries are capable of
delivering a very high current on discharge, so should not be shorted, as this
might result in sparking. Another feature is that their life is extended by
regular discharging and recharging
• Thus, any piece of equipment containing
rechargeable batteries should be regularly switched on and regularly recharged
• They
can fail without warning, back-up batteries for essential pieces of equipment
are required.Any questions be sent to drmmkapur@gmail.com
