Description: Portable Relay Testing Set is used for testing of all types of single phase relays, over current, over and under earth fault power voltage and directional relays. This portable unit comprises of variacs, ammeter, voltmeter, time interval meter and condenser and resistors for phase shifting. It is provided with suitable controls and terminals for following outputs: main outputs - 0-1/5/25/50/100A or 250V AC/DC; and auxiliary outputs -0-250 V AC or 0-25 A AC and 0-250 V Dc. The 4-digit auto-ranging time interval meter has the range of 0.0001 sec to 9999 secs with accuracy of 0.05%.
