ST-1546 Insulating Oil Dielectric Strength Tester

Product Introduction:

     The ST-1546 Insulating Oil Dielectric Strength Tester complies with GB/T507-2002 (1986), DL429.9, and DL/T846.7 standards. It is used to test the degree of physical contamination of insulating oil by water and other suspended substances. The testing method involves placing the sample in the dielectric strength tester and applying a uniformly increasing alternating electric field at a certain speed until the sample breaks down. Our company's research personnel, leveraging their advantages and through multiple field tests and long-term unremitting efforts, have developed this high-accuracy, fully digital industrial instrument. The machine is easy to operate, has strong anti-interference capabilities, and is safe and reliable. It can be widely used in industries such as power, petroleum, chemical, universities, commodity inspection, and scientific research.

Features:

◆ Equipped with a microprocessor, color LCD display, and unmarked key operation

◆ Automatically completes a series of operations such as voltage boosting, holding, stirring, standing, calculation, and printing

◆ Uses an automatic sine wave generation device and stepless voltage regulation for more stable and reliable test voltage

◆ Features protections such as overvoltage, overcurrent, and limit protection to ensure the safety of operators

◆ Utilizes an advanced dry-type transformer combination, compact size, lightweight, and easy to use

◆ Data is automatically stored and can be retrieved and printed at any time

◆ Unique high-voltage end sampling design allows test values to directly enter the A/D converter, avoiding errors caused by analog circuits and making measurement results more accurate

◆ The instrument's oil cup is made of special glass cast in one piece, eliminating interference such as oil leakage

◆ Multiple operation options, with programs including two national standard methods (GB507-1986 and GB507-2002) and custom operations to meet various user needs

◆ Built-in wide-range watchdog circuit prevents system crashes

◆ Standard RS232 interface for connection to a computer

◆ Paid calibration certificate provided by the Institute of Metrology
