What is KEMA testing?
The KEMA testing and inspections facilities include the world’s largest high-power laboratory, with the highest short circuit power of 10,000 MVA, and the world’s first laboratory capable of testing ultra-high voltage components for super grids, as well as the Flex Power Grid Laboratory, for advanced testing of smart …
What is a high voltage lab?
The High Voltage Laboratory has state-of-the-art equipment that can be used in the testing of materials and the study of different HV phenomena. The high number of MWB HV modules allows designing high-level detailed setups that can be used for experiments with fundamental HV theories.
What is KEMA approval?
KEMA approval is recognised as the key independent Dutch third-party accreditation, particularly when working on low voltage installation projects. KEMA approvals are issued by DNV GL, the Norwegian registrar and classification society headquartered in Oslo.
What is KEMA audits?
Why do we need high voltage laboratory?
In the field of electrical engineering the main requirement of high voltages is for insulation testing of various components in power system. This is why there is a need to generate high voltages in laboratories.
What is the highest voltage is available in HV Lab?
In addition to Kinectrics’ HV testing capabilities, the HV Lab operates an Environmental Testing Chamber capable of simulating cold fog conditions continuously, while monitoring the performance of insulation up to test voltages of 350 kV.
What does KEMA Keur mean?
The KEMA-KEUR mark demonstrates the electrical safety and quality of your products. In addition, it indicates that your products and manufacturing facilities are monitored regularly by DEKRA. It is recognized throughout Europe and other markets worldwide.
What is KEMA Keur certification?
What is high voltage equipment?
High voltage equipment typically include power transformer, switchgears, control equipment, communicating devices, insulators, and so on.
What is impulse test of transformer?
The purpose of the impulse tests is to determine the ability of the insulation of the transformers to withstand the transient voltages due to lightning, etc. Since the transients are impulses of short rise time, the voltage distribution along the transformer winding will not be uniform.
What is tan delta test of transformer PDF?
A Tan Delta test is performed by applying an ac voltage to a test cell of known gap, measuring the total current flow through the oil, and separating and comparing the reactive and resistance portions of the current passing through the oil.
