HZ2612 Low Voltage Short Circuit Impedance Tester for Power Transformer
Product Description
The instrument uses synchronized voltage/current sampling and high-speed digital signal processing for accurate measurement. It supports internal or external power supply and step-by-step measurement. For three-phase transformers, manual or automatic measurement is available. Data can be stored long-term in internal memory, and the instrument has a built-in printing function.
Key Features
Standards compliant - Fully meets DL/T 1093-2008 technical requirements.
Dual power modes - Internal supply offers 24V and 220V gears. Use 24V for initial testing to prevent excessive short-circuit current; use 220V only when test current is below 1A.
Strong anti-interference - High-performance embedded processing chips and digital narrow-band filtering effectively suppress power-frequency and high-frequency interference.
Panel Schematic
1. Wiring Terminals: The voltage and current measurement poles are connected to the transformer test voltage end. UA, UB, and UC are the voltage measurement wiring terminals, while IA, IB, and IC are the current measurement terminals.
2. External Power Supply: Used to input measurement power from an external source. The software interface should also be set to external power supply measurement mode.
3. Grounding Terminal: Safety grounding terminal.
4. Printer: Thermal printer that outputs measurement data. Paper replacement is as simple as pressing a button to open.
5. Display Screen: Large screen with a wide temperature band and special white-on-black LCD. The clear font is visible in sunlight, and all operations are displayed in Chinese.
6. Selection of Internal Power Supply Voltage: When using the internal power supply mode, the measurement voltage is generated internally by the instrument, offering a choice of 24 V and 220 V. Flip up for 24 V and down for 220 V.
7. Rotating Mouse: Used for up and down selection by rotating the mouse; press down to confirm.
8. Cancel Key: Used to cancel a setting or return to the previous step.
9. Contrast Control: Used to adjust the screen display effect.
10. Power Input: 220 V, 50 Hz AC power input.
