dc
For measuring electrical Current the electrical equipment used is Amphere meter. This equipment tells the current flow in the equipment.
48 volts is a convenient safe voltage to use, and telephone systems use a positive earth connection to minimise electroytic damage ot cables.
Gloves
Is used to reduce the short cct current levels within the ratings of the equipment on the load side of the reactor
Well that depends on the type of motor. DC motors use direct current DC and induction motors use alternation current AC.
Alternating current
For measuring electrical Current the electrical equipment used is Amphere meter. This equipment tells the current flow in the equipment.
A current transformer is an electrical device which is used to transform high current to a lower standardised current for control equipment used to messure current(amps)
Electrical current is measured using an ammeter.
the equipment that is used in a lab are goggles
+24 volts is not normally used for telecom equipment. -48 volts is the usual value. 48 was chosen as a compromise between safety and voltage/power efficiency. Minus was chosen over plus to manage corrosion effects of cabling in underground installations.
DC direct current
In plastic welding, equipment used includes plastic welders (some are ultrasonic) and as with any type of welding, protective equipment such as gloves.
48 volts is a convenient safe voltage to use, and telephone systems use a positive earth connection to minimise electroytic damage ot cables.
Large earth moving equipment, explosives, drilling equipment, tunneling equipment, etc.
A buck boost transformer is a type of transformer that is used to make adjustments to the voltage applied to alternating current equipment. These transformers are typically used in back up supplies or in tanning beds.
