Directions For Use

The secondary circuit of the transformer must be grounded. Make sure that secondary circuit is never opened while current is flowing in primary windings, otherwise dangerous high voltage will result. The grounding of secondary circuit eliminates error due to accumulation of electrostatic charges on the instrument.
Secondary winding should be short circuited and the line voltage should be cut when changing instruments or when not in use.
For the primary winding, to which the line of voltage is directly applied, use a wire insulated well enough to withstand the specified maximum line voltage.

Applications:

Suitable for Ammeters, Watt-meters, Power Factor meters and Protective Relays.
In addition to the above we can offer current transformers to your requirement with various combinations of ratios, burden, accuracy class

Current Transformers: FAQs

01. What are the key factors to consider when selecting a current transformer?

When choosing a current transformer, several factors are crucial:

Primary current rating: The transformer must be capable of handling the expected current flow.
Secondary current rating: The secondary current should match the requirements of the connected metering or protection device.
Accuracy class: The transformer’s accuracy class determines its suitability for specific applications.
Burden: The total impedance of the secondary circuit, including the connected devices, should be within the transformer’s specified burden.
Installation environment: The transformer’s construction and insulation should be appropriate for the operating conditions.

02. How important is proper installation and grounding of a current transformer?

Proper installation and grounding of a current transformer are essential for safety and accurate performance. The secondary circuit must always be grounded to prevent dangerous high voltages from occurring when the secondary is open-circuited. Additionally, correct installation ensures that the transformer operates within its specified parameters and provides reliable measurements.

03. How does MARSZ ensure the accuracy of its current transformers?

MARSZ current transformers undergo rigorous testing and calibration to meet specified accuracy classes. The use of high-quality materials and precise manufacturing processes contributes to the overall accuracy of the product.
