Inductive Voltage Testing Device

ED0202 Mid-Frequency Inductive Voltage Resistance Comprehensive Test Bench

Note: Focus on the physical equipment!

The test console allows for remote control of voltage regulators and transformers; it sets current-voltage range conversion, test item selection, overcurrent and overvoltage protection, real-time display of current and voltage, and voltage endurance timing.

The voltage and current meters on the console are both displayed by digital heads.

The measurement range of the output voltage meter is 0-20000V/100V; accuracy: 0.5 class.

The measuring range of the output current meter is 0-300A/5A; accuracy: 0.5 class.

The pressure regulator's output voltage gauge has a measurement range of 0-650V and an accuracy of 0.5 class.

The output voltage measurement range of the medium-frequency generator set is 0-800V; accuracy: 0.5 grade.

The three-phase voltage regulator is electrically adjustable for lifting and lowering from the control console, and features zero-point protection as well as upper and lower limit protection functions.

C: Features overcurrent protection and overcurrent reset functions.

D、The switching of standard current transformer (CT) taps is all done on the control panel.

E. The main control console includes an emergency stop device, allowing for the immediate disconnection of the main circuit in the event of an unexpected situation with the test item!

The master control console is equipped with a red alarm light and bell. The alarm light blinks when the main circuit is activated, and after the test is completed, pressing the bell button reminds the test personnel that the test is finished.

The complete control system consists of two parts: one part is the main control console, equipped with various indicator gauges, overload relays, and start/stop buttons; the other part is a switchgear cabinet composed of primary circuits including AC contactors, intermediate relays, circuit breakers, voltage transformers, and current transformers.
