Rish Delta VAF

On site programmable PT/CT ratios

It is possible to program primary of external potential Transformer site via (PT), primary of external Current Transformer (CT) on 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 can set the display in auto scrolling mode or fixed screen mode using front panel keys.

User selectable 3 phase 3Wire or 4Wire or Single phase Network (Option available with external aux only)

User can program on site the network connection as either 3 Phase 3 Wire or 4 Wire using front panel keys. In case of self powered Rish Delta either 3 Phase 4 wire or single phase network can be given.

Low back depth

The instrument has very low back depth (behind the panel) of less than 54 mm.

True RMS measurement

The instrument measures distorted waveform up to 15th Harmonic.

Four function keys

Using the four function key, it is possible to go desired parameter screen instantly.

RPM Measurement

The instrument display Rotation per minutes for generator applications. Number of poles can be set on site depending upon application requirement.

Hour Run, ON Hour

Hour run records the number of hours load is connected.
ON Hour is the period for which the auxiliary supply is ON.

3 line 4 digits LED display

Simultaneous display of 3 Parameters.

Onsite selection of Auto scroll / Fixed Screen

User can set the display in auto scrolling mode or fixed screen mode using front panel keys..

Min Max 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.

Energy Measurement (Import & Export)

Active Energy (kWh), Reactive Energy (kVArh), Apparent Energy (VAh). Any of the parameters can be assigned to optional Pulse output.

One line alphanumeric LED display (Optional)

In case of power failure, the instrument memorizes the last energy count. Every 1 min, the instrument updates the energy counter in the non-volatile memory.

Four function keys

Using the four function key, it is possible to go desired parameter screen instantly.

Enclosure Protection for dust and water

Conforms to IP 50 (for front face) & IP 20 (for back)

EMC Compatibility

Compliance to International standard IEC 61326.
