50kVA 150kV AC Withstand Test System for Transformer Insulation Defect Detection Power Frequency High Voltage Testing Equipment with Partial Discharge Analysis for Electrical Equipment

Product Description

Product Name: 50kVA/150kV Power Frequency PD-Free AC Withstand Test System

A high-voltage insulation problem does not always lead to immediate breakdown. Small internal discharge can appear at an early stage and gradually indicate deterioration of the insulation system. The 50kVA/150kV Power Frequency PD-Free AC Withstand Test System is designed to provide a testing environment in which insulation withstand performance and weak discharge activity can be evaluated during the same testing process.

The equipment can be applied to power transformers, instrument transformers, generators, bushings, surge arresters, GIS, capacitors, switchgear and other high-voltage apparatus. Its high-sensitivity acquisition capability helps capture weak partial discharge signals, providing useful information for identifying potential insulation abnormalities and reducing the possibility of missed defects.

Product Parameters

Product Advantages

• Early Defect Identification: Sensitive detection of weak discharge activity can provide indications of developing insulation problems.
• Combined Testing Approach: Allows withstand performance and discharge characteristics to be considered together.
• Broad Equipment Coverage: Designed for different categories of high-voltage apparatus rather than a single equipment type.
• Reduced Detection Risk: Sensitive signal acquisition supports more reliable identification of abnormal discharge.

Application Scenarios

• Transformer insulation diagnosis
• Generator insulation examination
• GIS and switchgear inspection
• Electrical equipment condition assessment
• High-voltage equipment commissioning
• Insulation quality verification

FAQ

Q1: What kind of insulation problems can PD detection help identify?
A: Weak partial discharge may indicate potential insulation abnormalities such as defects developing within an insulation system.

Q2: Does the equipment only perform PD testing?
A: No. The main testing function is power-frequency AC withstand testing, complemented by partial discharge detection.

Q3: Which equipment categories are supported?
A: Typical applications include transformers, generators, GIS, switchgear, bushings, capacitors and surge arresters.

Q4: What is the rated capacity and voltage?
A: The system is rated at 50kVA with a maximum AC test voltage of 150kV.
