| On site programmable PT/CT ratios |
It is possible to program primary of the external potential Transformer (PT), primary of external Current Transformer (CT) on site via front panel keys by entering into Programming mode. |
| User selectable CT Secondary 5A / 1A |
The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A using front panel keys. |
| User selectable PT Secondary |
The secondary of external Potential Transformer (PT) can be programmed on site from 100VLL to 500VLL using front panel keys. |
| User selectable 3 phase 3Wire 4Wire or Single phase Network |
User can program on site the network connection as either 3 Phase 3 Wire/4 Wire or single phase network using front panel keys. In case of self powered configuration either
3 Phase
4 wire or single phase network are available. |
| RPM Measurement |
The instrument display Rotation per minutes for generator applications. Number of poles can be set on site depending upon application requirement. |
| Limit switch (Relay) |
The instrument will trip the relay if the programmed parameter exceeds the programmed Trip Limits. |
| 3 line 4 digits LED display |
Simultaneous display of 3 Parameters. |
| Enclosure Protection for dust and water |
Conforms to IP 50 (for front face) or IP 65 option (for front with seal) & IP 20 (for back) & as per IEC60529. |
| Storage of parameters possible |
The instrument stores minimum and maximum values for System Voltage, System Current, Run Hour, ON Hour & number of Interrupts. Every 60 sec stored values are updated. |
| Four function keys |
Using the four function key, it is possible to go desired parameter screen instantly. |
| Onsite selection of Auto scroll / Fixed Screen |
User can set the display in auto scrolling mode or fixed screen mode using front panel keys. |
| Low back depth |
The instrument has very low back depth
(behind the panel) of less than 55mm
(without output options). |
| True RMS measurement |
The instrument measures distorted waveform up to 15th Harmonic. |
