ETCR048HA high-voltage clamp leakage current is suitable for high-precision detection of AC current, higher harmonic current, phase, electric energy, power, power factor and so on. With a unique automatic plug-in structure, it is easy to use, without disconnecting the line under test, non-contact measurement, safe and fast, especially suitable for line fault inspection instrument. Widely used in electric power, communications, meteorology, railways, oil fields, construction, metrology, scientific research and teaching units, industrial and mining enterprises and other fields.

The iron core of ETCR048HA high-voltage clamp current transformer is made of permalloy and adopts double-layer shielding technology. The influence of the external magnetic field is extremely small, which ensures high-precision, high stability and high reliability of continuous measurement without interruption. The transformer can output current and voltage signals, and the range, output signal, and output interface of the transformer can be customized according to customer requirements.
