Purpose
Primary Injection Test Set DTE-16M (High-Current Circuit Breaker Test Equipment)
The DTE-16M is a high-performance primary injection test set designed for circuit breaker testing and verification of time–current characteristics in the extended range of 20 A to 16,000 A. This advanced breaker testing equipment ensures precise measurement and recording of current and operating time for high-power devices.
Main Applications
- Current injection test for circuit breakers up to 16 kA.
- Testing and certification of protective and measuring current transformers (CT testing).
- Relay calibration and verification (overcurrent and thermal relays).
- High-current fuse testing and evaluation.
- Use as an adjustable AC current source up to 16 kA for laboratory and field applications.
Key Features
- Mounted on a transport trolley – simplifying operation and relocation at testing sites.
- Galvanic isolation between power supply and output circuits guarantees operator safety.
- Versatile circuit breaker test equipment covering breakers, CTs, relays, and fuses.
- Extended range and capacity compared to DTE-10M and DTE-14M models.
