Features
On site programmable PT/CT ratios
It is possible to program primary of 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 or 4Wire or Single phase Network
User can program on site the network connection as either 3 Phase 3 Wire or 4 Wire or single phase network using front panel keys.
In case of self powered Rish Delta only either 3 Phase 4 wire or single phase network are available.
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 54 mm. using front panel keys.
True RMS measurement
