Testing & Inspection

For electrical equipment before being put into operation, it is necessary to check the features of the equipment to ensure safety and reliability to avoid problems when put into operation at high voltage and the equipment. After a period of operation, it must be overhauled, maintained, and checked periodically for long-term stable operation of the equipment.

V.T.E.C.H Electrical Technology Co. LTD owns the modern test instruments transfered from many well-known manufacturers of HV/LV electrical instruments such as PowerPD (USA), IPEC (UK), N4L (UK), b2 High Voltage (Switzerland), Tentech (USA), Powersight (USA), Sonel (Poland), DET (Ukraina), IBEKO Power AB (Sweden), Alpha Moisture (UK), Constant (Australia), Omicron (Austria), Quartzteq (Switzerland), RF (Japan), Doble (US) … Some Latest Diagnostic Technology Solutions such as Online Patial Discharge Testing, Sweep frequency respond analyzer for Transformers, LIRA technology for underground Cable… Our High technology services are serving for Power Companies, Transmission Companies, Gas & Oil Industry, Industrial Factory, … contributed important roles in early diagnostic and preventive maintenance programs to prevent the catastrophic failures and loss of revenue.
