Chongqing Gold Mechanical & Electrical Equipment Co.,Ltd
YD series HIPOT tester is applied to test the insulation ability of electric power equipments and insulation materials at power frequency high voltage. The insulation test result of the tester is go or not go. Also the YD series HIPOT tester is a universal power source in HV test. The maximum output voltage and capacity could be customized according the requirements of custom.The tester is consists of single HV transformer and main control box. There are two kinds of HV transformer according to the insulation materials of the HV transformer.They are dry HV transformer and oil HV transformer. For the dry HV transformer the insulation material is epoxy resin.For oil HV transformer the insulation material is insulation oil. The dry HV transformer has a smaller size and less weight than oil HV transformer. But the maximum output voltage is less than 100kv for dry HV transformer. The functions of the main control box are voltage output regulation, protection in emergency and voltage/current value indication

Osborne Transformer Corp.
Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.

Kingrun Instrument Co., Ltd.
applying ±90V voltage on the winding of the transformer demagnetized and get the voltage value on the terminal and the current value in the winding to draw the hysteresis characteristic curve. This method can be used for linear quantitative analysis of residual magnetism in transformers, and fast demagnetization can be achieved by tracking hysteresis curves. The analyzer can measure magnetism residual rate before and after demagnetization.

Neutronics Manufacturing Co.
NMC''s Transformer BDV Oil Test Set is a portable unit as per relevant Indian Standard Specification IS :6792 :1992, suitable for operation on 230 / 240 Volts, A.C. 50 Hz. A three core flexible cable is connected to the unit with three pin socket to connect the mains. The H.V. Transformer is a completely dry, resin encapsulated with two H.V. terminals with mounting saddles. The center point of the transformer is earthed, so that the voltage of each terminal to earth is only half the test voltage.

Kingrun Instrument Co., Ltd.
transformer neutral grounding resistor is the vital need in medium voltage AC distribution network that are also called by different names like Neutral Earthling Resistors. They are taken into use to limit the current that would flow through the neutral point of a transformer or generator in the event of an earth fault. They are also used for resistance grounding of connected generators and transformers.

Kvtester Electronics Technology Co.,Ltd
High precision instrument for measuring characteristic parameters of transformer capacity, no-load and load. The instrument is a multi-function measuring instrument, which is equivalent to the usual two kinds of test instruments: the transformer capacity tester + transformer characteristic parameter tester. The utility model can precisely measure a series of power frequency parameters of a plurality of transformers, such as the capacity, the type, the no-load current, the no-load loss, the short circuit (load) loss and the impedance voltage.

AYA-Instruments
These transformers are encased in a thermoplastic case with the core and windings encapsulated in resin. They are designed for line-to-line operation but may also be used in line-to-neutral or line-to-ground configuration at 58% of rated voltage. It is recommended that a 1.6 Amp fuse be used in the secondary to protect the transformer.
