Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the WESHINE Transformer Ohmmeter (VS-3110 series) of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the Megger Transformer Ohmmeter (MTO) series of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

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

Shanghai Jiuzhi Electric Co., Ltd.
Conventional AC test transformers are especially designed for testing objects of medium capacitance. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (inductive voltage transformers). The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space.

Megger Group Ltd.
The transformer turns ratio test, or TTR test, confirms that the transformer has the correct ratio of primary turns to secondary turns. Using this test correctly can help to identify tap changer performance, shorted turns, open windings, incorrect winding connections and other faults inside transformers. Megger’s range of TTR testers are robust to withstand the harsh conditions that some transformer testing in. The range includes varying features to simplify and speed up testing as well as 3 phase TTR testers and PT and CT TTR testers.
