Current Injection

Product Description
The 50A-3PH is a three-phase injection system providing commissioning and maintenance engineers with a flexible system for testing protective systems. It has an easy to understand panel layout and a simple user interface. The status of every function can be seen at a glance, and there are no complex menus to navigate.

The unit has a range of outputs allowing injection of currents as low as a few Milli-amps and as high as 50 amps. Voltages up to 18 volts are available on the main outputs. Three true RMS metering ranges are provided, allowing the full scale of the meter and trip level to be set independently of the selected output. Industry standard safety connections are used on all inputs and outputs for convenience, reliability and safety.

The 50A-3PH is a comprehensively protected by overcurrent, duty cycle and thermal trips, and keeps the user fully informed of any trip condition. Auxiliary outputs and inputs are fuse protected.

Benefits
An auxiliary metering input is provided and can measure voltage, current, frequency, and the phase between any of the current outputs and an external voltage or current.

The timing system is very flexible without compromising ease of use, allowing trip times, reset times and reclose times to be quickly measured to a high degree of accuracy. Two independently isolated contact inputs are provided, and the timing system may also be used as a stand-alone timer.
 

• Over and under current relays.
• IDMT relays.
• Auto-reclosers.

When used in conjunction with a DVS3 3-phase voltage source the 50A-3PH may be used to test most types of protection requiring three voltages and three currents including:

• Directional overcurrent relays.
• Distance protective relays.
• Phase angle relays.
• Power transducers
