Product Information

MCC1010 and MVC1010 1000 A AC Current Clamp
The MCC1010 and MVC1010 1000 A AC Current Clamp is a non-contact current sensing clamp used for measuring AC current up to 1000 A. It has a CAT IV 600 V current measurement rating and a 1 mA/1 A sensitivity with a rated burden of

The clamp has large jaws that can fit cables up to 52 mm and is suitable for leakage currents. The output terminals are protected with a voltage limiting circuit to ensure safe-to-touch voltage under all rated conditions. MCC1010 and MVC1010 are rated to CATIV 600 V, according to the international standard IEC 61010.

Product Usage Instructions

When using the MCC1010 and MVC1010, it is important to note that the rated terminating resistance (burden) of 1 must be provided by the instrument connecting to the clamp. The clamp is intended to clamp around a single phase of the asset being tested and not phase + neutral, as this could yield incorrect results due to current flowing in opposite directions. Keep the clamps separate wherever possible to improve the quality of multiphase current measurements.

An ammeter measuring up to 1 A can be connected directly to the MCC1010 or MVC1010. When measuring current up to 1000 A, the ammeter reading will be 1 A due to the 1000:1 step-down ratio of the clamp. If using a TRMS multimeter, the voltage reading will be TRMS because of the accuracy and crest factor performance of the clamp.

When completing resistance measurements, both clamps must be used. The MCC1010 induces a current through a conductor while the MVC1010 measures the voltage drop across the conductor. This way, non-contact resistance measurements can be undertaken using the MCC1010 and the MVC1010 clamps.

The MCC1010 and MVC1010 are simple to use and have applications with various instruments including power quality analyzers, oscilloscopes, motor testers, clamp enabled earth testers, attached rod technique (ART), stakeless testing, data loggers, and digital multimeters.

DESCRIPTION
The current probe is designed for measurements of AC currents up to 1000 A with a 1000:1 step-down ratio.
The probe offers excellent accuracy (0.3% error at full range) and small phase shift (0.7° at full range) so it can be used for metering of power, energy and power quality applications. Such high performance is achieved because the magnetic cores are made from high-permeability FeNi alloy.
The rated terminating resistance (burden) of 1 Ω must be provided by the instrument connecting to MCC1010 and MVC1010. The output terminals are protected with a voltage limiting circuit ensuring a safe-to-touch voltage under all rated conditions.
MCC1010 and MVC1010 are rated to CATIV 600 V, according the international standard IEC 61010.

APPLICATIONS
The MCC1010 and MVC1010 are non contact current sensing clamps which is simple to use and has application with the following instruments:

Power quality analysers
Oscilloscopes
Motor testers
Clamp enabled earth testers
Attached is Rod Technique (ART)
Stateless testing
Data loggers
Digital multimeters

CLAMP USAGE
The MCC1010 and MVC1010 are intended to clamp around a single phase of the asset to be tested and not phase + neutral because this would yield an incorrect result as a consequence of current flowing in opposite directions. Keep the clamps separate wherever possible, to improve quality of multiphase current measurements.

An ammeter measuring up to 1 A can be connected directly to the MCC1010 or MVC1010. A current of 1000 A will result in the ammeter reading 1 A (1000:1 step-down ratio).

The MCC1010 and MVC1010 generate 1 mV output signal across 1 Ω burden resistance for every 1 A of primary current, so if using a multimeter, one with an mV AC range is required. Dedicated earth testers instruments like Megger’s DET range, DET3TC, DET4TC and DET4TCR will need to ensure the input resistance and measurement circuitry are appropriate for the 1 mV – 1 V input range and a primary current limit of 20 A.

If using a TRMS multimeter the voltage reading will be TRMS because of the accuracy and crest factor performance of the MCC1010 and MVC1010 clamps.

Both clamps must be used when completing resistance measurements. The MCC1010 induces a current through a conductor. The MVC1010 measures the voltage drop across the conductor. This way, non-contact resistance measurements can be undertaken using the MCC1010 and the MVC1010 clamps.
