TRIP CIRCUIT AND DC VOLTAGE SUPERVISION RELAY (TS-101)
TRIP CIRCUIT AND DC VOLTAGE SUPERVISION RELAY (TS-101)
- Continuous supervision of trip circuits with circuit breaker in the open and closed position. Monitors loss of auxiliary voltage, DC trip voltages, and circuit interruptions.
- Indicating flag, (LED)
- Tripping output contacts, N/O or N/C.
- Plastic casing for flush mounting.
- Delayed drop-off to prevent spurious operation.
- Does not require any external resistor.
- Mechanical Flag to indicate loss of DC Voltage or any other fault.
Under and Over Frequency Protection Relay (ELFR-50)
Under and Over Frequency Protection Relay (ELFR-50)
Frequency Protection Relay takes the reliable measurement of frequency. User can set the over and under frequency limits through selection variables, crossing these limits shall operate a relay rated at 5A AC.
Battery Impedance Monitoring Relay (ELBI-220)
Battery Impedance Monitoring Relay (ELBI-220)
- For DC-Voltage systems, it protects the system against deterioration of battery impedance. The cause of which could be terminal corrosion, loose terminal connections, sulphate deposit etc.
- On pressing of start button, it measures the resistance between battery terminals by drawing 10 amps for a short duration and measure the impedance simultaneously.
CAPACITOR TRIP UNIT (ELC-110)
CAPACITOR TRIP UNIT (ELC-110)
- CAPACITOR TRIP UNIT (ELC-110) takes AC supply for input, converts it into DC Voltage. At the absence of AC Supply it holds enough power to supply 130 VDC and 3Amps for 3 to 4 seconds.
- A discharge button is provided, in case maintenance work needs to be done.
BATTERY EARTH FAULT RELAY (ELEF-110)
BATTERY EARTH FAULT RELAY (ELEF-110)
- BATTERY EARTH FAULT RELAY (ELEF-110) is used in DC-Voltage systems, it protects the system against leakage of current to earth.
- It continuously monitors the resistance between earth and both the poles, and as the resistance
drops to a preset level the contact makes and the visual indication comes on. - The Relay is available in 48,110 and 220 Voltage range
The Hygrostat Relay (ELH-220)
The Hygrostat Relay (ELH-220)
- The Hygrostat Relay ELH-220 is a microprocessor based intelligent relay that monitors and control the inside humidity level of the panel containing electrical equipment.
- It does that by measuring the humidity level, compares it with the preset limit and energizes the heater through its dry contact, whenever needed, till the humidity level drops to the desired level.
- It has built-in thermostat (adjustable) and a contact to energize the external heater.
Transformer Temperature Gauges (XTP3)
Transformer Temperature Gauges (XTP3)
- Transformer Temperature Gauges XTP-3 is for the protection of heavy transformers against overheating. However, it may be used for protecting large motors and generators as well.
- It is utilized in conjunction with a semiconductor-based thermal sensor, which is placed at a strategic spot in the equipment to detect sustained operating temperatures above normal.
- The rugged sheet metal body allows for its mounting in panels next to the transformers primarily designed.
