Zero Phase Reference Standard ZPS 1101

• Broad-band operation up to 100th harmonic of mains frequency
• Optional scalable current up to 240 A (720 A)

Description

Zero Phase Standard is a specially designed broad-band four-terminal resistor optimized for negligible Reactance component of the complex Impedance.

The Zero Phase Standard has nominally zero phase angle between the current flowing through the resistor and the respective voltage on its voltage terminals. The resistor is designed to operate with current up to 1A or with voltage up to 150V with nominal Resistance 150 Ohm.

The Zero Phase Standard is dedicated for calibration of Power and Energy Reference devices. The current range of the device can be extended up and down by Precision Electronically Compensated Current Transformer CMR-I 2x30.
