Alarm Relay Dealers

Fuse Auto Changeover Systems continuously monitor various fuses provided in Railway Signalling Installations. The System not only monitors the fuses, but also changeover to a Spare Fuse (provided within the system) automatically on failure of the Main Fuse. The system simultaneously monitors the status of both the Main and the Spare fuse and provides audio visual alarm on failure of any fuse. INTEGRA has developed fuse auto changeover system as per RDSO Specification No. RDSOSPN2092012 Rev 2.0 Type I Module with 32 nos. of G type Fuse from 0.6 Amp to 4 Amp Capacities Type II Module with 24 nos. of G type Fuse from 4 Amp to 10 Amp Capacities

We are associated with renowned transportation providers to ensure delivery of consignments is carried out without a glitch and in a timely manner. Keeping in compliance with the international standards, we ensure that the raw materials used for varied products are 100% certified and quality approved. This helps us in maintaining a set standard of our products.   Exclusive Features of our Buchholz Relay & Oil Surge Relay Body is made of single piece die cast aluminium alloy instead of casted CI body, in which micro cracks may give leakage at any time. No need to treat for porosity, since no micro cracks are developed. With mercury or magnetic reed switch; NO or NC contact as required. Built-in test facility for checking continuity of both - alarm and trip circuits.   Available in 3 sizes for pipe diameter: 25 mm (GOR - 1) 50 mm (GOR - 2) 80 mm (GOR - 3) Compact & hence, low weight design with high efficiency. We also manufacture Oil Surge Relays for protection of O.L.T.C.

Oil surge relay rs 2001 type: rs 2001 connection: with flanges with 4 holes switching system: no alarm: normaly � open disconnection: normaly � open oil flow tripping the flap valve 1,20 ms.

We at Sumesh petroleum aim to provide end-to-end solutions for complete Transformer Overhauling and Maintenance.Transformer Overhauling – The basic meaning of Overhauling is to examine or go over carefully for needed repairs. In the process of Overhauling Engineers open the whole Transformer to do the needful cleaning, repair and replacement, in short the process includes overall inspection including lifting of core and coils.

The Buchholz Relay is one of the most essential protective devices to protect equipment such as transformer, capacitors, on-load tap changers, etc. It detects abnormal working of the components inside the equipment and consequently minimizes the spread of any damage to the equipment active part by disconnecting faulty apparatus before large scale damage occurs to the apparatus or other connected apparatus.

We are offering oil surge relay. The protective oil surge relay (osr) is used to protect the malfunction developed inside the on load tap changer (oltc). It is installed in the pipe between oltc head and oil conservator. any malfunction builds pressure which leads to increased oil flow. This protective relay triggers the tripping circuit when the oil flow exceed the specified limits, thus making the transformer to be turned off and contain the damager to the oltc and transformer. osr is fitted with special reed switch which assures rust free contacts even after decades after installation thereby is alert for operation. This osr is designed and tested for very intensive seismic levels. osr is a part of the oltc and its properties are subject to iec 60214.

Mercury switch type 25-80mm and oil surge relay. We have attended number of Transformer in the last l0 years to the various electricity Boards & utility in all over the country & running satisfactory since attending.
