Description
T&R Test Equipment is a market leader in the field of current
injection equipment. The range includes secondary injection units with 50A
output capability up to 6000A primary injection systems. All have true RMS
metering, a flexible timing system, and an easy to understand user
interface.
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 back-lit display on the 50A-3PH is
bright and clear with a wide viewing angle. The results of a test
can be seen here as they appear on the display. |

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.
The unit has a range of outputs
allowing injection of currents as low as a few mA and as high as 50A.
Voltages up to 18V 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 connectors are used on all inputs and outputs for
convenience, reliability and safety.
The 50A-3PH is comprehensively
protected by overcurrent, duty cycle and thermal trips, and keeps the user
fully informed of any trip condition. The 50A-3ph can be used to test many
types of single and three phase secondary protection including:
| |
- Over and under current relays.
- IDMT relays.
- Auto-reclosers.
- Time delay relays
|
|
- Earth fault relays.
- Miniature circuit breakers.
- Power relays.
- Tripping relays.
- Thermal relays.
