Current Protection Relay
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.

Frequency Sensing Relay
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.

Latching / Bistable Heavy Duty Power Relays
The voltage pulse will activate the relay to pull-in or release the contacts. The latching relay / bistable relay will hold its contactposition till the next voltage pulse. Below latching relays / bistable relays are designed for demanding heavy duty applications.

Monitoring Relays
A Monitoring Relay is a protective control device. The basic functions are to receive input signals, monitor and determine them, and output an alarm signal if a set value (threshold) is reached. Monitoring Relays monitor power supplies (voltage, current, power, phase), temperatures, and other analog signals and detects abnormalities in machines and equipment by determining values against alarm thresholds.

product
Pilot Wire
The concept is based on the need to improve the performance of existing pilot wire protection schemes by increasing reliability & availability as well as adding an over current guard function. This can be achieved at considerably lower cost than the replacement of the existing proven protection relays & change over to a fibre optic communication channel.
