The Doble Instruments Transformer Turns Ratio Capacitor (TTR) is an accessory for the Doble M4000 and M4100 Power Factor Insulation Analyzers. It is used to measure the turns ratio of transformers by applying a high voltage stress test to the turn-to-turn insulation. The TTR is also used to detect shorted turns or winding damage.
The TTR consists of a capacitor bank that is connected to the primary and secondary windings of the transformer. The capacitor bank is charged to a high voltage, and the current flow through the capacitor bank is measured. The turns ratio is then calculated from the current flow and the voltage applied to the capacitor bank.
The TTR is a valuable tool for ensuring the safety and reliability of transformers. It can be used to detect problems with the turn-to-turn insulation that could lead to a transformer failure. The TTR is also used to comply with industry regulations that require periodic testing of transformers.
Here are some of the features of the Doble Instruments Transformer Turns Ratio Capacitor:
- Measures the turns ratio of transformers in accordance with IEEE C57.12.90 standard
- Detects shorted turns or winding damage
- Supports both single phase and three phase transformers
- Easy to use and portable
- Durable construction for long life
Here are some of the applications of the Doble Instruments Transformer Turns Ratio Capacitor:
- Testing the turns ratio of new transformers before they are put into service
- Testing the turns ratio of transformers in service to identify problems such as shorted turns or winding damage
- Determining the need for transformer maintenance or repair
- Complying with industry regulations that require periodic testing of transformers
