Ashida Electronics Pvt. Ltd is started in 1970 by technocrat

Mr. Manohar P. Kulkarni. Soon we established our self as

reputed manufacturer of non-destructive testing

instrument for Geo-logical application. From 1985

onward we started manufacturing of Protection

Relays for Power Systems. In 1998 our company was

certified with ISO 9001and year 2000 we shifted in our

new full-fledged production plant of 25000 sq feet. stIn 2002 we were awarded 1 prize of very prestigious

Government of India - Nation Award for special

efforts in R&D.

ASHIDA SCADA Software coupled with ASHIDA s

FCCM series of modules forms a scalable & flexible

ASCADA-SAS System This system can be employed to

make a satellite sub-station completely un-manned,

controlled from a central location Such a scheme can

serve as an Important tool in Energy Management &

Audits and also completely encompass the functions of

Event Sequence Recording.

This Intuitive GUI based system is built on

internationally standard components. Any available

communication medium (ea. PLCC, VHF, dial-up,

Dedicated cables, etc.) can be used to link the Sub-

station equipment to the central software using

appropriate communication interfaces The modular

approach gives a benefit of add-on simplicity with

maximum economic benefit.

ASHIDA RELAY TESTING UNIT VARIABLE FREQUENCY (ARTUVF)

Variable AC current: - 0-200Amp with 250VA.

Variable AC voltage : - 0-300 VAC.

Variable DC voltage : - 0-360 VDC.

In-built auxiliary power supply: - 30 / 110 / 220VDC.

Fix AC voltage : for direction/power relay testing - 63.5 V / 110 V AC.

Time measuring : Micro-controller based unit with 1ms resolution.

Special provision : Relays ON Delay / OFF delay time measurement.

The ARTUVF/S unit is specially designed to suit relay

testing designed of power station testing engineers. The

ARTUVF/S is a cabinet, which has all the necessary

functions for relay testing viz. Auxiliary source, Time

Interval Meter up to 1ms resolution etc. After adding

optional phase shifter and phase angle meter, the

ARTUVF/S become a complete relay-testing unit for

testing of all available Static / Electromechanical TSS
