JRV-161 JVS make Auxiliary Relays contact is often used in a relay logic circuit, or for some other part of the motor control scheme, typically switching 120 Volt AC power instead of the motor voltage. ... They are not fuses; that is, it is not their function to burn open and directly break the circuit as a fuse is designed to do.It's a way to open or close a circuit breaker. There are open and close coils in large, multiphase breakers. These can be activated by applying auxiliary voltage to them via the auxiliary relay. This allows control over the breaker remotely or automatically to apply or remove power from a load.

JRD-011 JVS Make Restricted Earth Fault REF Relay are current operated Microprocessor based, differential relays which work on the high impedance principle. An external series stabilizing resistor is used with this relay to make it a voltage operated relay. The voltage setting of the relay is adjusted to be higher than that developed by the current transformers used for maximum external fault conditions. JRD 011 is a single pole relay where as JRD 013 is a triple pole relay.

• The sensing current is converted to voltage by an internal resistor and this voltage is fed to a harmonic network which is tuned to fundamental frequency. The output of filter is fed to voltage comparator. When the sensing current signal at the fundamental frequency exceeds the set value,the comparator gates a train of pulses to the processor. The program residing in the CPU performs the function of control and also gives output signals for relay and LED driver circuits. The operation of the relay is indicated by the glowing of a 'Red' LED,which has to be reset manually by means of a 'RESET' push button provided on the front of the relay. A 'Trip Test' push button is also provided in the relay to enable testing of the trip and alarm circuits. When this push button is pressed, the output element of the relay is energized and its contacts close to energize the trip and alarm circuits.
• The relay will not operated at third harmonic currents upto 25 times the setting

JNP-098 JVS make Numerical Over Current Relay provides directional over current protection for power systems. Relay operating time is determined by selecting definite time characteristics or one of the four inverse time characteristics i.e. (3s normal inverse, 1.3s normal inverse, very inverse and extremely inverse). The operating region is defined by the characteristic angle selected. The relay measures the current and voltage from each of the phases and if the phase angle in the operating zone of the relay, then the relay extends trip signal.

JND-040 JVS Make Numerical Transformer Differential Relay provides differential protection for power transformer. The relay measures the line current of each phase from each of the windings of the transformer. Relay calculates the differential current (Id) and restraining current (Ir) per phase. The differential characteristics define the operating and the restraining regions. The shape of the characteristics defined by Initial pickup (ik), SLOPE1 (DF1), SLOPE2 (DF2) and break point (kp) are programmable. If ‘Ir’ is less than ‘kp’, then characteristics is defined by ‘DF1’ and is applicable for small differential currents. If ‘Ir’ is greater than or equal to ‘kp’, then characteristics is defined by ‘DF2’ and is applicable for large differential currents. If the operating point i.e. (Id, Ir) is within the operating region, then the relay trips. The relay provides programmable 2nd and 5th harmonic current restraint, which, exist when transformer is energized and over excitation condition exists respectively. The relay provides stability on external “line to line” and “line to ground” faults. The relay has in-built vector group compensation selection and CT ratio correction, hence the usage of external interposing CT can be avoided.
