AC High Voltage Test Set

Rectifiers & Electronics, an ISO 9001: 2008 company, offers AC High Voltage Test Set. These high voltage high capacity testers are specially designed for testing cables and electrical equipment as per national and international standards. The testers have been designed and developed in-house. During manufacturing each unit is tested at multiple stages, thus ensuring consistency and best quality. These instruments are cooled air cooled, oil cooled or air and oil cooled combined as per requirement, and have been manufactured up to 800 kV and 2000 kVA. Brief details: a double wound step up transformer is the most important part of the equipment; the transformer is wound with high quality enamelled copper wire and polyester film/paper is provided between the layers; CRGO step core is used for light weight and efficient transformer; control – (a) The unit can be manual/motorised control for voltage variation and push button controlled for HT actuation, (b) The unit can be microprocessor based complete with on board memory, printout facility, programmable features, etc., and (c) The unit can be PLC based complete with computer, HMI, memory, printer, etc., for operation; metering – the metering can be provided via primary measurement, tertiary winding measurement, or via capacitive voltage divider for direct HT measurement; termination – one end at earth potential and other at HV insulator with Tan delta test capabilities; and protection – (a) Switch fuse unit is provided for higher capacity, (b) A fast acting DC relay actuates to isolate high voltage in case of fault or when current exceeds the preset value, (c)The unit has zero start interlocking arrangement to ensure that HV will not actuate unless variac is at zero position, and (d) Test cage door interlock wherever required.
