Weshine Electric Manufacturing Co., Ltd
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores.

Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.

● Microprocessor-controlled.● Measures Earth Resistance without the need for poles in the ground or external measuring wires.● Earth measurement uses the real earth current path and the current generated by the electric network, without the need for any disconnection.● The Earth Resistance displayed is exactly the earth resistance that the earth current will need to go through if an earth fault occurs. No need to add all the bonding points and connection paths resistances.● Displays voltage supply at the transformer (Line to Neutral), without loading the transformer. Displays voltage between Line (Phase) and Earth (Ground), without drawing any current.● Measures the impedance of the line itself so you can analyze and differentiate between the multiples paths of the wiring.● Measures the Neutral Impedance. Single one smart push button operation; ON, Test, Scroll trough results and menus.● Checks wiring integrity (LEDs).● Auto off/auto ranging (software ranging). ● Combined prospective short circuit current, loop, individual wire and Earth Tester.● Voltage test L-N and L-E.● Loop test for L-E and L-N and PSC.● Enables analysis of constituent components in L-E and L-N loops giving resistance of earth, neutral wire, live wire and transformer winding.● Display can be customized for large orders.
