Megger EGIL Circuit breaker tester

Product introduction

The EGIL circuit breaker tester is intended for circuit breakers with one contact per phase. The EGIL incorporates features commonly found on more complex test systems, but is designed to be smaller, simpler to use and less expensive than other similar test sets. The EGIL has three channels connected together on one side and two separate time channels for measuring auxiliary contacts. Events at parallel contacts are recorded and displayed simultaneously via pre-insertion resistors.

FEATURES AND BENEFITS

▪ Suitable for testing timing and travel on all circuit breakers with single interrupter per phase
▪ Extremely easy-to-use and reliable
▪ Two separate timing channels for measurement of auxiliary contacts
▪ Analogue measurement channels for travel transducers or general voltage/current measurements
▪ Static and dynamic resistance measurements along with the SDRM201 accessory

DESCRIPTION

EGIL™, which incorporates benefits gained from experience with our larger instrument, is intended for circuit breakers with one contact per phase. Smaller and simpler, EGIL is equally versatile – and EGIL's price makes it attractive to small power plants. Moreover, it provides an ideal supplementary instrument for maintenance departments at large power companies.
To simplify on-site connection, the EGIL comes with ready-made multi-cable sets for both the main and auxiliary contacts. Coil currents are measured automatically and presented, together with other readings, immediately after testing on the display window or via the built-in printer. Additionally, the EGIL has a built-in breaker control unit that sets the instrument automatically for the next sequential breaker operation, making it easy and intuitive to use.
Using the EGIL with the the SDRM and the SDRM accessory enables you to perform static and dynamic resistance tests and the EGIL can also be equipped with an optional USB interface for communication with a PC and the CABA Win circuit breaker analysis software.

EGIL is intended primarily for testing high-voltage circuit breakers at medium-level voltages. There must not, however, be more than one break per phase since the time channels are not galvanically isolated. Contact times are recorded for main contacts, pre-insertion resistor contacts and auxiliary contacts. Coil currents are also recorded.
Besides the actual measurement values several parameters according to IEC standards are calculated and shown in the report, e.g. closing and opening time, difference between phases, over-travel, CO and OC time (and others).
