Product Introduction & Application Purpose
1. 30KVA Intelligent Power Frequency Withstand Voltage Test System
This AC power frequency hipot test system consists of intelligent control console and oil-immersed high voltage test transformer. It is widely used for power frequency withstand voltage test of high voltage switchgear, insulator, transformer, bushing, cable and other power equipment. It verifies the insulation strength of electrical components under rated power frequency high voltage, detects insulation defects, air gaps and hidden dielectric breakdown risks. Core Application: Factory routine test, type test for medium-high voltage electrical apparatus, insulation strength verification.
2. Partial Discharge Detection System
The partial discharge (PD) test system is deployed inside the high voltage shielding test area. It detects tiny partial discharge signals inside high-voltage equipment such as switch cabinets, transformers and mutual inductors. Partial discharge is a key indicator of insulation aging and internal defects. The system captures ultra-high frequency PD signals, locates discharge source and evaluates long-term insulation reliability of power equipment. Core Application: Partial discharge type test for high voltage switchgear, GIS, transformers, insulation material research and third-party certification testing.
3. High-Voltage Switch Dynamic Characteristic Tester
The high voltage switch dynamic characteristic tester is portable precision measuring instrument for vacuum circuit breakers, load switches and disconnectors. It records switching time, closing & opening speed, stroke, contact bounce time and coil current curve. It evaluates the mechanical operating performance of high-voltage circuit breakers, identifies mechanical jamming, spring fatigue and contact asynchronous problems.
Core Application: Circuit breaker factory test, incoming inspection, maintenance test of high voltage switch-gear, mechanical characteristic type test.

FAQ Section (Google People Also Ask)
Q1: What is power frequency withstand voltage test used for? A: Power frequency withstand voltage test is to apply rated AC high voltage to power equipment, check the insulation capacity and find insulation defects such as crack, air gap and contamination of insulators, cables and switchgears.
Q2: Why do we need partial discharge test for high voltage switchgear? A: Partial discharge will gradually erode insulation and cause equipment failure. PD testing detects tiny internal discharge signals before breakdown, to assess the long-term insulation reliability of high voltage equipment.
Q3: What parameters can the high voltage switch dynamic tester measure? A: It tests opening time, closing time, contact bounce time, contact travel, opening/closing speed and operating coil current curve for vacuum circuit breakers and high voltage switches.
Q4: Does Shanghai Demiks provide on-site after-sales commissioning service? A: Yes. Shanghai Demiks Power Technology provides full lifecycle service including on-site installation, commissioning, technical training, maintenance and calibration for high voltage test equipment for customers across China and overseas.
