Relay Test Set

Sharmasons Sakova Instruments, a leading manufacturer of electrical testing equipment for the electric power utility industry, offers a Relay Test Set. Unique features include: AC current voltages output of 0-1/5/25/50/100 A or 250 V AC/DC; auxiliary AC voltage up to 250 V and AC current up to 25 A; auxiliary DC voltage up to 250 V; timer and phase shifter provided; and compact and portable unit. The set is capable of testing of all types of single phase equipment, over-current, under and over voltage, leakage current, power, differential and directional relays etc. Other fields of operation are plotting excitation curves and ratio tests of CTs and PTs. The set comprises of the auto variable transformers, current transformer, contactor, automatic cut-off, electronic time interval meter, capacitor and resistors for phase shifting, operating switches and meters for output parameters, housed in a cabinet made of FRP. Suitable switches are provided for selection of voltage and current ranges and type of relay contacts, viz., NC/NO. The output current and voltage are continuously variable. The output is automatically cut off as soon as relay under test operates. The time interval meter indicates the time taken by the "Relay Under Test" to operate. Separate terminals are provided for output voltage and current ranges and relay connections. The toggle and push switches, indicators, voltmeter, ammeter and variac knobs are provided on the control panel. A sturdy carrying case is provided for easy transportation. The TI meter can also be programmed to measure pick-up and dropout time of contactors, independently.
