This relay is a frequency monitoring relay with four stages of adjustable frequency pick up & drop out points. Each frequency set point can be set for under or over frequency operation & has an independent time delay driving an output relay. An undervoltage lockout is used to disable the four frequency outputs when the voltage falls below a preset level. Each of the four setting stages has a rate of change of frequency (ROCOF) element with an independent time delay.

A Timer Relay is a combination of an electromechanical output relay and a control circuit. The contacts will open or close before or after a pre-selected, timed interval. Time delay relays are initiated or triggered by one of two methods:*Application of input voltage/auxiliary supply will either initiate the unit or make it ready to initiate when a trigger signal is applied. *Applying a trigger signal is used to initiate the unit after input voltage has been applied. This trigger signal can either be a control switch (dry contact switch) or a power trigger (voltage).

Neutronics Manufacturing Co.
NMC’s Microcontroller based Automatic Voltage Regulating Relays (AVR Relays) are latest technology based Relays used for regulating the secondary voltage of Power Transformers with On Load Tap Changer (OLTC). The Parameter settings are made through the front panel keys & are stored in NVRAM. Independent time delays can be set for first control pulse & subsequent pulses. Built-in Tap displays Tap number of Power Transformer. OLTC is blocked for UV, OV, OC, CF, Min/Max Tap Positions & Tap Fail . in manual mode, Tap Raise/Lower can be achieved through front keys. In TEST mode, Relays, Display and LED indications can be checked. A pair of contacts are available for Raise, Lower, UV, OV, Manual Mode, CF, TF & OC. There are two nos. of 5 Amps C.T.’s available, one for the Over Current blocking and L.D.C. & other for measuring the Current.

The main earth fault protection relays in distributions systems, power stations & large manufacturing / processing plants can fail to detect a high impedance break down to earth causing hazard to human life & potential damage to plant & equipment. In these & other situations demanding extra sensitive earth fault protection, using solid state techniques, can be applied to detect earth currents down to 0.5% of the CT nominal current.The relay is tuned to reject 3rd & higher harmonic frequencies to avoid problems under quiescent conditions. An adjustable time delay is built in to provide stability during switching & other transient disturbances & to allow adequate grading with other protection systems at high fault current levels.
