Semi Automatic Meter Test bench
The calibration and certification of electricity meters are important functions, which are generally carried out by the electricity supply companies, electricity boards and energy meter manufacturers.
Due to the semiautomatic nature of the test, it is economical and capital investment is less and more suitable for Indian Conditions.
The test bench is easy to operate and as a precise result is obtained at the same time, cost for testing is reduced.
Test bench can be used to test Ferrari Meters and electronic KWH Meters.
* 10/20,10/40 meters can be tested simultaneously, therefore more productivity.
* Accuracy of reference standard can be 0.05% or 0.1% therefore all types of energy meters can be tested.

Relay Testing Equipment
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 are generally of electro - mechanical type.
