Coils with a variety of winding turns and intermediate
taps. A suitable choice of coil enables all experiments to
be performed safely at low voltage. Simple whole-num-
ber winding and intermediate tap ratios allow the trans-
former laws to be derived in clear and understandable
fashion.
1. Safety instructions
•
The safety of operators and of the coils themselves
can only be guaranteed when they are used accord-
ing to the instructions.
•
Depending on the set-up of the transformer, it may
be possible to come into contact with dangerous
voltages at the secondary coil.
•
Coils 8497430, 8497440, 8497450 can be subject to
high or low voltages when used as secondary coils.
They are not suitable for experiments performed by
students.
•
The resulting magnetic fields can cause damage to or
even destroy electrical/electronic components and
equipment or electromagnetic storage media. Such
items must be kept away from the coil by at least the
amount specified for safety.
•
Always use safety cables for experiments.
•
Do not exceed the maximum voltage over any length
of time.
•
If the coils should become overloaded, they must be
allowed to cool before switching on the current again.
•
Do not cover the air vents.
•
Any modifications to the transformer set-up must be
made with the primary voltage switched off.
•
Do not open the coils’ cases.
