Operations of the relay can be tested by means of a test, button which energies the output relays & LED’s after set time delay with the channels set to underover frequency operation. Access to the test push button requires removal of the front cover. This test facility should normally only be used with the relay trip circuits isolated, ARMO UFT frequency relays are used to monitor the frequency of an electrical system. Due to inadvertent splitting of inner connection in power system, isolated areas of the system may become deficient in the generation & frequency of the same may drop considerably giving rise to emergency conditions.

These are used for the inspection of hand lamps etc. and are preferably for low voltages. ARMO manufactures transformers for stepping down the 230 volts line supply to 24 V, suitable for hand lamps. These transformers are of single phase double wound construction.

These transformers rectify the fluctuation in line voltage. They are available for both single and three phase supplies and in any capacity up to 500 KVA. For single phase supply the normal input is between 180 to 250 V, output being 240 V. For three phase supply the input is between 380 to 440 V, and output 415 V. They are also custom manufactured as per the specifications and needs.

Any Double Wound Transformer is inherently an ISOLATION TRANSFORMER as the primary and secondary are isolated from one another through insulation.  However, modern   machines and   systems need a truly isolated, clean and stable power requirement.  This is ensured by an Ultra Isolation Transformer (UIT).  It provides for total electrical and electro static isolation with most effective screening of spikes, surges and transients.  Further, it gives a true isolated local neutral and dedicated earth which are very essential for modern machines. Ultra Isolation Transformer attenuates common mode noise and transverse mode noise and provides for noise or interference free power.  In principle, UIT only transfers 50 Hz power by transformer action through mutual inductance.  It prevents transfer of RF and HF disturbances with extensive insulation between primary and secondary.  The insulation levels withstands HV breakdown strength of 2.5 KV and gives a DC galvanic isolation of above 1000 mega ohms.

ARMO-UFTR Frequency relays are used-to monitor the frequency of an electrical System. Due to inadvertent splitting of inner connection in power system. Isolated areas of the system may become deficient in the generation and frequency of the same may drop considerably giving rise to emergency conditions. In order to maintain control of system under this low frequency emergency,some form of graded load shedding is needed. ARMO-UFTR relay is used to detect such conditions and initiate load shedding to prevent complete system collapse. Type UFTR-41 consists of two/three definite time fully independent frequency measuring stage and one df/dt stage. Type UFTR-51 consists of two/three definite time fully independent frequency measuring stage and one df/dt stage. Separate   Auxiliary relays are provided which get energized after the respective time delays (In case of df/dt the tripping frequency gradient). Tripping indications and reset push button are provided on the front of the relay. The relays are suitable for any application in industrial plants and to generators where definite time under over frequency protection with df/dt stage is required. Internal timers are provided for each operating circuits and separate aux relays ensure maximum flexibility of application. Two terminals are provided for the voltage input to the frequency sensing circuit. The measurement of the frequency is digital for which only the zero-crossing of the system voltage and not its amplitude, are of consequence.
