Description
Resonant test system HVT-60/80-500 is designed for high-voltage testing of high-capacitance objects such as generator stator windings, busbars, cables etc. The testing can be performed with either a DC or an AC voltage at industrial frequency, in automatic or manual modes.
Technical performance: Using manual button operation, can meet the complex test requirements and repeated for different test products. The display panel uses a 7-inch touch screen with the function of overvoltage and overcurrent protection.
Main features: By setting tripping and over voltage, over current limit value, to protect the test object. It can set the output limits of the high voltage reactor/transformer and the output limits of the excitation transformer. Automatically and manually tune or manually set the reactor compensation, setting the voltage increasing speed as a percentage of the final boost time or in KV/sec according to IEC 60060-1. Detailed status-fault information marked with colored highlights enables accurate fault detection and safe operation of the system. Voltage measurements conform to IEC 60060-1, showing true RMS values or U/√2.
