Um teste «tan delta» a um transformador permite avaliar com precisão o estado do isolamento. Permite detetar precocemente humidade oculta, prevenir incêndios repentinos e garantir o funcionamento seguro da rede elétrica durante muitos anos.
Os detetores de descargas parciais online permitem-lhe identificar com segurança falhas ocultas no isolamento. Evita assim interrupções de energia dispendiosas, deteta precocemente tensões dinâmicas e protege o seu equipamento crítico contra avarias repentinas.
Um detetor de descargas parciais é um dispositivo de teste que identifica pequenas faíscas elétricas no interior do isolamento de alta tensão. Utiliza sensores para captar ondas ultrassónicas, tensões de terra e sinais eletromagnéticos.
SF6 gas inside your switchgear is the only thing standing between safe operation and a major disaster. An SF6 gas analyzer gives you the power to see inside the tank. It tells you if your insulation is pure, if it is dry enough to stop an arc, and if there is any hidden damage happening right now.
VLF testing is the only safe way to test modern XLPE power cables. It stops space charge damage, follows IEEE standards, and saves your expensive electrical assets from sudden failure.
Choosing the right VLF tester requires checking the frequency, matching the cable voltage, and comparing brand data. KVHIPOT gives you the best balance of price, power, and reliable field performance.
Substation commissioning is hard work. Bad transformer tests cause huge
VLF cable testing is a safe and smart choice for your cables. By choosing the correct frequency, you find hidden defects easily and keep your power network running perfectly.
Very Low Frequency (VLF) testing for all medium voltage cables during commissioning and diagnostics. SEC acceptance requirements are generally framed based on the principles of international standards IEEE 400.2 and IEC 60502-2.
Testing large, high-voltage electrical equipment like long XLPE cables, GIS, and large transformers is a serious challenge. AC Resonance Test Systems is essential test equipment for hv electrical equipment .
