The secondary injection test for protection relays is a common testing method used to evaluate the performance and functionality of protective relays in electrical systems.
There are some tests for insulation oil testing include Breakdown voltage (BDV)test, water content test, acidity test, Dielectric Dissipation Factor test, Interfacial Tension test, Flash Point test, Viscosity test, Relative Density Test, Furan Analysis , Dissolved Gas Analysis (DGA)ect.
This article will talk about the methods of cable testing .The cable testing focused on insulation layer and the leakage , withstand voltage , dielectric loss and partial discharge characteristics of cable insulation
This article introduces battery discharge testing information and the guide of battery discharge capacity test ensure to help you successfully proceed discharge testing to identify the battery state of health (SOH）
Transformer Preventive maintenance is crucial to ensure the reliable operation, extend their lifespan, and prevent unexpected failures. This involves regular inspection, testing, and servicing. Here’s a detailed overview of transformer preventive maintenance tests .
In response to the frequent occurrences of transformer short circuit accidents, we need to delve into understanding the underlying causes, examining the short circuit conditions , and strategizing to minimize their frequency and impact,checking the transformer short circuit testing.
when it comes to the utilization of 35 kV XLPE cables, the issue of abnormal partial discharge poses a significant challenge. Power outages resulting from this problem accelerate cable damage, leading to economic losses for industry development and hindering sustainable industry growth. Consequently, when analyzing partial discharge issues with 35 kV XLPE cables
VLF testing is considered more suitable for assessing the withstand capability and insulation quality of modern cables with polymer-based insulation. It provides a more realistic and less damaging test method compared to DC testing. The VLF testing method allows for a more accurate evaluation of the cable’s condition and remaining life expectancy.
Battery Charger Discharger Introduce A battery charger discharger is a
What is the difference between VLF and hipot?
VLF Testing is a AC hipot tester that perform the withstand and diagnostic testing for test object at very low frequency 0.1 Hz to 0.01 Hz . It is applied for HV/MV cable, motor and generator and other high capacitive loads.
