Megger’s range of dc insulation testers, MIT515, MIT525, MIT1025 and MIT1525 are targeted at original equipment manufacturers and industrial companies. The top of the range MIT1525 performs insulation resistance tests up to 15 kV with a 30 TΩ maximum resistance and an accuracy of ±5 % from 1 MΩ up to 3 TΩ. The MIT515 offers IR, DAR and PI functions but has no memory functionality. MIT525, MIT1025 and MIT1525 have a full suite of test modes as well as on-board memory and the ability to stream data / download data to a PC / laptop. Instrument productivity is a focus of the MIT range, which offers rapid charge batteries and operation from an ac source if the batteries are dead. Rapid charge batteries enable >60 minutes testing after a 30 minute charge.

Safety rating is not compromised on the MIT range with all terminals safety rated to CAT IV 600 V to 3000 m (5 kV, 10 kV) or CAT IV 1000 V to 3000 m (15 kV). A range of 5 kV and 10 kV test leads are available plus dedicated 15 kV test leads, which are double insulated with clips designed for 15 kV creepage paths. The 15 kV leads are supplied in a carry bag. Suitably rated HV gloves and other personal protection equipment are required to be worn when testing.

The MIT range shares dual case design, which includes a tough outer case to protect the tester from knocks/drops and an inner fire retardant case. The IP rating is IP65 case closed eliminating moisture and dust ingress.

An intuitive user interface ensures no lost time remembering how to use the tester. Simplicity of operation is achieved with two rotary switches and the large backlight display which enables multiple results to be shown simultaneously. A graphical Quick Start Guide is provided inside the lid to assist first time users.

Five preset voltage ranges are provided in insulation test mode, plus a user settable lock voltage range. Preconfigured diagnostic tests include Polarization Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Step Voltage (SV) and Ramp Test.

Test leads are double insulated (t) with clamps rated at 3 kV (t) equivalent to 6 kV single insulation for the medium clip leadset and 5 kV (t), equivalent to 10 kV single insulation for the large clip. The 15 kV leadset is insulated to 15 kV.

Applications:

The Insulation Resistance (IR) test is a quantitative test, which indicates the effectiveness of a product’s electrical insulation. Applications include cables, transformers, motors / generators, circuit breakers and bushings. Common insulation tests are the “spot test”, a 1 minute IR test and a 10 minute Polarisation Index (PI) test, where PI is the ratio R10min / R1min and is temperature independent.
