Zc-630 three-phase harmonic analyzer is a multi-functional power measuring instrument developed by our company, which can measure three-phase voltage and three-phase current 1-63 times harmonic, and display odd or even harmonic separately by list or spectrum diagram.
It is very suitable for the field use of differential detection and start-up test, such as electric energy measurement, power inspection, power inspection, transformer maintenance, relay protection, etc. It can be used as training tool and teaching instrument for wiring discrimination in electric power colleges. At the same time, it is also suitable for large-scale power consumption enterprises such as chemical industry, metallurgy, mining, railway, etc.
When zc-630 three-phase harmonic analyzer is used, some measuring wiring methods are as follows:
1. Y-type wiring
Clamp UN terminal (wire color is black) to the zero line of voltage signal to be measured. Clamp U1, U2 and U3 terminals (wire color is yellow, green and red) to a and B, C three phase line; if only one phase voltage needs to be measured, clamp UN terminal to the zero line and U1 terminal to the phase line to be measured; if two-phase voltage needs to be measured, clamp UN terminal to the zero line and U1 and U2 terminals to the phase line to be measured.
The arrow on the side of the current clamp indicates the current direction. Clamp I1, I2 and I3 current clamps (the color circle on the clamp line is yellow, green and red in turn) onto a, B and C three-phase phase lines; if only one current needs to be measured, clamp I1 current onto the current line; if two current needs to be measured, clamp I1 and I2 current onto the current line to be measured.
2. Delta type wiring
Clamp UN terminal (wire color is black) to phase B, U1 and U3 voltage terminal (wire color is yellow and red in sequence) to phase A and phase C.
The arrow on the side of the current clamp indicates the current direction. Clamp I1, I2 and I3 current clamps (the color circle on the clamp wire is yellow, green and red in turn) onto a, B and C three-phase phase wires.
Zc-630 three-phase harmonic analyzer adopts the button type operation, can automatically switch the range, maintain the measured data, store the measured data, realize the large capacity storage, and output the vector diagram, with powerful function and simple operation, it is worth purchasing.
