transformers are rated by
primary voltage, secondary voltage and VA rating
when you find the secondary of the transformer 'open' the usual cause is
a shorted load in the circuit
L1 to L2 indicates an applied voltage of
240 v.
the primary of a transformer is connected to the
line
the secondary of a transformer goes to the
load
step-down transformer is identified because
E decreases
step-up transformer is identified because
E increases
L1(H) to L2 indicates an applied voltage of
120 v.
L1/N/L2 indicates an applied voltage of
120/240 v.
