Descriptions:
ETCR080/080A Large Caliber Clamp Leakage Current / Current Sensor
is well designed and manufactured for measurement of AC current, higher harmonic current, phase, electric energy, power and power factor, by adopting the latest CT technology. Its large caliber 80mm×80mm can clamp electric cable of Φ80mm, or 96mm×4mm flat cable and steel earth wires. It is portable, clamp designed, no need to disconnect the circuit, non-contact measurement, which means safer and faster. It can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, electric power quality analyzer, high precision multi-meter, widely applied in those fields as electricity, communications, meteorology, railroad, oilfield, construction, measurement, scientific & research teaching institutes, industrial and mining establishments.
ETCR080 Large Caliber Clamp Current Sensor’s clamp core is made of special alloy, adopt the double magnetic shielding techniques, can almost shield the influence from external magnetic field, to ensure the high precision, high stability and high reliability of perennial uninterrupted measurement.
Feature:
1. The clamp structure does not require power failure or disconnection of the tested line, and is especially suitable for on-line field testing.
2. Support non-contact measurement, easy to operate, fast, safe and reliable.
3. With high quality alloy core, it has stable performance, high and strong anti-interference ability, and is suitable for complex interference environment.
4. It is suitable for high detection of AC current, high harmonic current, phase, electric energy, power, power factor, etc.
5. With the new CT technology, it can connect phase detection analyzer, industrial control device, data recorder, oscilloscope, harmonic analyzer, power quality analyzer, high digital multimeter and so on.
6. It is widely used in electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields.
7. Its core is made of ferronickel alloy, and the influence of external magnetic field is very small, which ensures high , high stability and high reliability of uninterrupted measurement all the year round.
8. The current sensor can output current and voltage signals. The range, output signal and output interface of the transformer can be customized according to customers'requirements.

Principle and Structure
The sensor induced output a current I1, the current I1 generate voltage U on the external sampling load resistance RL, so the measured current I can be calculated by measuring U. Output voltage 0-2.5V. Among them, I=n×I1; U=I1×RL. n is the coils turn (current ratio).
