As the rated secondary current in case. Burden can be denoted in va or in ohms.consider that to a pt. The first step is to determine the saturation voltage for the current transformer (ct) in question.

Burden Of Cable Can Be Calculated As “Current Square X Resistance Of Cable Per Length X 2 Times The Length Of Cable” I.e.

When performing vt burden, the secondary voltage is injected (typically 120v) and the current (meter inline) is measured to determine the burden in va. Knowing your burden and calculating your va is the key to finding the proper current transformer for your application. Use the 3 phase and single phase transformer sizing calculator below to calculate primary and secondary full load current.

If A 250/5A Ct Is.

Cable va = (2l x r x i^2). The burden of the transformer is normally denoted in va. The main purpose of the burden resistor is to protect the current transformer.
