Overview: the GD-300D reactor electrical parameter tester is an instrument dedicated to measuring the electrical parameters of single-phase or three-phase reactors. It can simultaneously measure the AC phase voltage RMS, average voltage, current RMS, active power, reactance and inductance of single-phase or three-phase reactors, with a measuring accuracy of 0.5 class.
Key features: a 240 x 64 dot-matrix backlit LCD simultaneously displays the single-phase or three-phase phase voltage RMS, average voltage, current RMS, active power, reactance and inductance. Multi-screen menu operation is provided for the user to choose from, operation is convenient, and all parameters are calculated automatically. Voltage and current transformer ratios can be set from the keypad so that primary measured values are displayed directly. The test date and the transformer serial number can be entered and are latched on power-down. Power can be measured in the low power factor range.
Interfaces and protection: the instrument is equipped with a printer interface and a serial RS232 computer interface, and the print format follows the standard record (Chinese character) format. Anti-interference performance is strong, an overload alarm indication is provided, and reliable over-voltage and over-current protection makes the instrument suitable for working in field verification environments.
