High Quality Cheap Split Core Clamp Lv Electric Meter Current
Transformer
Porduct introduction and application :
Current Transformer (CT) is used to transform the high AC current
to small easily manageable values. They're connected with the Panel
Meter or Relay and they can help to measure the current or protect
the equipments. Low voltage current transformers are manufactured
as of two types for measuring CT.
Safety :
Current transformers are often used to monitor hazardously high
currents or currents at hazardously high voltages, so great care
must be taken in the design and use of CTs in these situations.
The secondary of a current transformer should not be disconnected
from its burden while current is in the primary, as the secondary
will attempt to continue driving current into an effective infinite
impedance up to its insulation break-down voltage and thus
compromise operator safety. For certain current transformers this
voltage may reach several kilovolts and may cause arcing. Exceeding
the secondary voltage may also degrade the accuracy of the
transformer or destroy it. Energizing a current transformer with an
open circuit secondary is the dual of energizing a voltage
transformer (normal type) with a short circuit secondary. In the
first case the secondary tries to produce an infinite voltage and
in the second case the secondary tries to produce an infinite
current. Both scenarios can be dangerous and damage the
transformer.
