Fully automatic three phase energy meter test bench offered by us comply with the standard of IEC 60736 testing equipment for electrical energy meters and IEC62053 standard with electricity metering equipment. These are used in test functions like Warm up, Basic error test, standard deviation (S) in error test and repeatable error tests. Some other test functions these are used in include:

Test Function:
* Latent test (no load test)/automatic and manual operation with seek mark automatically.
* Initial test (starting test)/automatic and manual operation with seek mark automatically.

Structure and Features:The water meter test bench is made up the platform, clamps, back and front pipe, flow counter group, standard measuring instrument and the outlet valve. When the inlet is connected with the stable water source, the water will get to the standard measuring instrument through the straight pipe. Compare the value of the checked water meter with that of the standard measuring instrument, the valve error that the water meter reads will be acquired.
Technical Parameters:
1. Checking gadget precision: 0.2%
2. Water meter diameter : 1520254050
3. Testable water meter indicators: For overall performance test (for the production)
4. Instant flow indication: glass rotor flow counter, the actual accuracy should be no lower than 2.5%;
5. Measuring instrument volume:
15-25mm, (10L+10L) 20L, (50L+50L) 100L;
15-50mm, (10L+10L) 20L, (100L+200L) 300L;
6. Working Pressure: 0.25-0.4MPa;
7. Clamp flexibility: 15-25mm checking gadget: 500mm, 15-50mm checking gadget: 60mm

Features :-
The Relay Testing Equipment is a portable apparatus which is designed for checking the operating characteristic of protective relays on site. Ever present in every day operation of electrical power system is the possibility of the occurance of faults . Since a relay in the system is called into action to deal with a fault only once in a long while, its failure to operate correctly on that occasion means Severe damage to plant or waste of money spent on installation. Periodic Field testing is the best way of ensuring the integrity of the protective relays. But the position is complicated because of the fact that the protective relay is solely concerned with fault conditions and hence it cannot readily be tested under normal operating conditions. The relay testing equipments are secondary injection testing sets which simulate the common fault conditions under which a protective relay will be called into positive function. These testing sets can be used for testing almost every kind of protective systems from simple over current relays to more complicated distance relays. But not all power supply authorities need such a wide range. Hence Lomas offers relay testing equipments of various types such as RKY-1, RKY-2 and RKY-3 with specific testing capacity to suit any particular group of protective relays.
Application :-
Field testing of Electrical [AC] relays which

Underground power cable fault locator suitable to locate U/G power cable faults form 440 volts to 400KV. Cable fault locator (Surge generator) has been primarily designed to produce high voltage surges for pre-location of under ground power cable fault in combination with Reflectometer T-510.

Three-phase four-wire multi-function electronic meter is a fully programmable and very powerful meter that can satisfy your most demanding request. It can provide you with extra function of reactive energy measurement, instant variable of current and voltage for each phase and load profile. The accuracy for active energy measurement can be 0.5s. Its reliable performance under heave load and high harmonic conditions make it a superb choice for the gate of power station or large power consumer. It complies with IEC 62053-11.

Lomas Primary Injection Test Set is a versatile compact apparatus designed to give standard output current upto 1000 Amps from an input of 230 Volts AC. Test Sets to suit any other input voltage or with higher output can be catered for by order. This wide range of variation in output is obtained with smooth regulation and least wave form distortion. By using the Primary Injection Test Set, functional checks involving high currents can be carried out at low cost and with inherent safety requiring minimum precautions.
Application:-
It has wide field of applications in testing supply net work, high current circuits and phantom loading.
