High Voltage Testing of electrical equipment covers a wide range of techniques depending on the nature of the equipment and the type of test required. High Voltage testing is usually performed to qualify the device to operate safely during rated electrical conditions, a way to check the effectiveness of its insulation. The objective sought during the high voltage testing will determine the type and amount of voltage applied and the acceptable current flow. 
We provide a complete and broad range of High Voltage Test Equipment.

A dielectric strength tester is a device used to evaluate the insulating properties of materials, particularly in electrical equipment. It measures how well an insulating material can withstand high voltages without breaking down. Here are some key points about dielectric strength testers:

Purpose

• Insulation Testing: Ensures that insulation materials in electrical devices can handle high voltages without failing.
• Quality Control: Used in manufacturing to verify the quality of insulating materials.

How It Works

• High Voltage Application: The tester applies a specified high voltage across the insulation material.
• Measurement: It measures the current that flows through the insulation. If the current exceeds a certain threshold, it indicates a breakdown.

Types of Tests

• Dielectric Breakdown Test: Determines the voltage level at which the insulation fails.
• Dielectric Withstand Test: Evaluates the insulation under high voltage for a set duration to check for weaknesses.

Key Specifications

• Voltage Range: Can test across a wide range of voltages, from a few hundred volts to several kilovolts.
• Safety Features: Often includes features like automatic shut-off and indicator lights for safe operation.

Applications

• Electrical Equipment: Used for transformers, cables, motors, and generators.
• Manufacturing: Quality assurance for insulators, circuit boards, and other components.

Safety Considerations

• Always follow the guidelines mentioned in the manual.
• Ensure proper grounding and insulation of the tester itself.
• Use personal protective equipment (PPE) when conducting tests.
