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.
